Following Giulia Corsi's transfer, her deputy Roberto Ardenzi becomes the new commissioner of the X Tuscolano. During the inauguration ceremony, a gang of ferocious robbers breaks into the villa of a rich notary, easily deactivating the alarm system. One of the criminals shoots the professional's twenty-year-old son in cold blood, killing him. The cruel action sparks the rebellion of the only foreigner in the group, the Romanian Artur, who is killed after he announces his intention to leave the gang.

Following an action conducted with the new commissioner Roberto, Mauro is taken hostage by the two brothers from Puglia led by the Neapolitan Gabriele, responsible for bloody robberies. Alessandro Berti of the Scientific Police offers himself as bait, allowing Roberto to hide and be taken to the hideout where his friend is about to be executed. After a terrible firefight, Mauro is freed by his colleagues.

The intuition of the new commissioner of the X Tuscolano Roberto is not wrong: behind the apparently casual death of the model Eva Paulin there is something more. The young woman, with the complicity of her brother Milo, stole precious objects from her rich clients. Milo has the commissioner receive a notebook that Eva had kept, before dying before his eyes.

Francesca, found by her husband Roberto in a pool of blood in their home, must undergo emergency surgery. Both she and the baby are at risk of losing their lives. While Luca, Anna and Irene, investigating a strange accident with a dead person, discover that it is a rape with robbery involving one of their colleagues, Francesca regains consciousness and tells her husband about the attack she suffered at home.

The newborn Francesco, son of Roberto and Francesca, is saved after a long operation. He is immediately celebrated by his siblings Michele and Mauretta and by the agents of the X Tuscolano. The new commissioner understands that he must deal with a character from the past, Cesare Carrano, today an important builder and instigator of the attacker of Francesca by Maiorca. He is also the father of Ruggero, the murderer of Milo that Roberto wounded before the escape, now a fugitive.

The new inspector of the X Tuscolano Irene Valli finds herself involved in a robbery in the store, where she and her nephew Stefano, eleven years old, happen to be. The two criminals do not hesitate to kill the owner of the store and beat the boy. With the excuse of wanting to treat him, Irene manages to make Stefano escape, who immediately calls Mauro. When the officers arrive, one of the criminals flees, taking a customer hostage.

The 10th Tuscolano is dealing with a thorny affair involving a rising politician: his blue car has hit and killed an immigrant. Roberto does not give up and tenaciously sets out on the trail of the killer Ruggero, son of the building contractor Cesare Carrano. Mauro asks his friend Ardenzi for explanations about a secret that he has kept from him until now while, with Irene, he tries to prevent the fugitive from escaping.

Ruggero Carrano is in prison and the prosecutor Forti authorizes the interrogation by the commissioner of the 10th Tuscolano. But the father of the murderer and his right-hand man are preparing a plan for a spectacular escape, while Mauro and Irene investigate the case of a sixteen-year-old who died of an overdose; the surprise is that the boy turns out to be the son of a friend of Mauro, whom he protected years before.

The 10th Tuscolano is in turmoil over what happened during Ruggero Carrano's spectacular escape. Everyone questions their own life: Luca goes to visit his dying father; Parmesan reacts to his hypochondria; Vittoria and Ingargiola get closer again. Roberto confronts Cesare Carrano, but there to protect him from himself is the faithful Alessandro Berti.

Carrano's right-hand man kills the members of the commando that allowed Ruggero's escape and now demands more money. The leader of the group manages to save himself: when Luca and Alessandro arrive at the crime scene, the head of the forensic team understands that the massacre is linked to the criminal organization headed by the Carranos. Thus begins a hunt for the survivor coordinated by Roberto.

While Irene and Anna investigate a villa robbery that ended in tragedy, Roberto asks Alessandro to remain on the force at the X° Tuscolano. With his help and the collaboration of Parmesan and Luca, the commissioner tries to decipher the code of the notebook written by Ruggero Carrano, finally in prison after Gabrielli's arrest.

Alessandro Berti accepts the proposal of the commissioner of the 10th Tuscolano to work in tandem with Irene on the case of a murder that hides a trafficking of newborns. Roberto must deal with the legal expedients of the lawyer who defends Carrano: the request for a calligraphic expertise on the notebook that contains the details of the complex criminal organization managed by the entrepreneur, turns out to be a dangerous trap.

The 10th Tuscolano is busy hunting down two girls in their twenties who, in the space of a few hours, uncovered, burgled a boutique and stole a spider. The two seem intent on having a memorable day, but the youngest is eight months pregnant. Meanwhile, Roberto tries to corner Maiorca who has destroyed the coded notebook, the main evidence in the trial against the Carranos.

On the eve of the trial against Ruggero Carrano, in which Roberto should participate as the main witness for the murder of Milo Paulin, Carrano's machinations do everything to discredit the new commissioner. This is how Ardenzi ends up being investigated by the disciplinary team for the murder of one of their operatives, whom he threatened several times after the destruction of the coded notebook.

A young Lithuanian, Jelena, turns to the X Tuscolano. The girl, in shock, has just arrived in Italy with a friend and her sister, all three convinced of entering the world of entertainment. She managed to escape but the other two remained, drugged, in the hands of an Albanian couple who intend to force them into prostitution. The agents know they have little time, while Roberto helps Tiberio, Mauro's father, to face a big problem.

Cesare Carrano is studying a plan to get his son Ruggero out of prison, sentenced to twenty years for the murder of Milo Paulin. Parmesan receives from Roberto the task of demonstrating the responsibility of the entrepreneur, head of a large drug trafficking ring. Irene and Alessandro investigate the murder of a young courier in love with a married colleague.

While the criminal entrepreneur Carrano organizes his revenge, supported by Patriarca and his lawyer, the X° Tuscolano is mobilized for the kidnapping of the son of a very rich cement manufacturer. The kidnapper acts with original methods and does not seem so interested in the ransom he has asked for the same day. Vittoria and Ingargiola are instead dealing with a champagne thief.

After the latest developments in the Carrano case, Roberto decides to take a break to spend some time with his family. He leaves the district in the hands of Alessandro Berti who, with Anna and Irene, tackles the investigation into a badly cut batch of heroin. There are already two drug addicts on the brink of death. During the investigation, Valli loses her professional detachment and brings her personal history into the case.

Investigating an arson attack, Alessandro and Irene meet a colleague from the explosives department who suspects a young but repeat offender. Simonelli takes it personally because he saw his best friend die during a fire set years earlier by the same deranged man. But Irene realizes that things are less straightforward than they seem, while Roberto manages to arrest the perpetrator of the car bomb commissioned by Patriarca.

During a graduation party, a young and beautiful university professor is drugged and raped. But when she wakes up, Viviana doesn't remember anything and Luca and Anna will have to find out who took advantage of her. Meanwhile, Roberto, who has discovered Patriarca's home and hidden documents inside that concern a nursery, gets back on the trail of Cesare Carrano.

Cesare Carrano is declared a fugitive, along with his accomplice Patriarca. The entrepreneur's villa is seized and Parmesan and his nephew Christian are tasked with archiving all the objects. Meanwhile, Anna and Luca investigate the alleged accident that caused a Russian immigrant to fall from the fifth floor, discovering a universe of marginalization and degradation.

Irene collaborates with Anna and Luca in the investigations into the disappearance of fourteen-year-old Daniela. The case will bring back Anna's painful past. The confession of an accomplice of Patriarca, who was arrested, forces Roberto to track down Francesca: in fact, the boss has very dangerous intentions towards them.

Irene and Alessandro deal with the murder of an actor, an alcoholic now adrift, found murdered in his own boat. His ex-wife will help them solve the case.

Roberto and Alessandro monitor the movements of the lawyer Grimaldi, the legal defender of Carrano, still at large with Patriarca. The other agents of the X Tuscolano are busy with the almost fatal attack on the young brother of a famous boxer. The investigations bring to light the boy's passion for clandestine betting and suggest the involvement of Nino who the night before almost lost an important match.

Until the very end, the challenge between Ardenzi and Carrano, long-time enemies, reserves sensational twists. And it turns out that not everything is as it seemed.

The new commissioner Fontana introduces himself to the agents of the X° Tuscolano and the new inspector Marchetti. He must protect a collaborator of justice, Nina Neri. The police are looking for Jacopo, a three-year-old boy taken from his mother at the supermarket.

Young Angela is raped at night by three masked men, just outside a gay nightclub. Fontana entrusts the case to Luca Benvenuto. Angela has recognized by the voice a boy who frequents her gym and Luca infiltrates it.

Two drug addicts rob a bar where Inspector Marchetti is, and steal his gun. That day, a ministerial inspection is underway at the district and Marchetti risks suspension. Alessandro helps his friend recover the weapon.

Alessandro and Raffaele investigate the serious accident that happened to sixty-year-old Mario Fabiani: it seems that the car he was driving was hit by a boulder thrown from the overpass above. Meanwhile, Luca notices that his neighbor Nick, a child who has become fond of him and Anna and who always stays at their house, has clear signs of abuse on his body. Nick lives with his mother Emilia who is summoned for checks at the X° Tuscolano.

Irene is in Manila and Sacha's instrument shop for her nephew Stefano's guitar when a parcel bomb arrives that causes a tremendous explosion. Who could have it in for the two brothers and why? In the meantime, Nina has been tracked down by her father's right-hand man, Morace, due to Berti's carelessness. Morace is already in Rome and Fontana decides to interrogate Vanessa, Nina's friend and her only link with Calabria.

Massimo, a ten-year-old boy, follows a stranger in a white van. His anguished father Lucio reports his disappearance to the X Tuscolano. The investigation leads Anna to relive the trauma she suffered as a child with her stepfather and to make a serious error of judgment. Meanwhile, Commissioner Fontana, worried about Nina's escape, convinces his friend Vanessa to come to Rome to make an appointment with her and put her back under protection.

The X Tuscolano is entrusted with an operation of the utmost importance: to take to the incinerator 50 kilos of pure drugs seized from Rambaldi, an internationally wanted drug trafficker. The Cerrone brothers, two fanatical criminals, are also interested in the load that they want to resell to Rambaldi himself and will do anything to steal it from the police officers. Meanwhile, Nina is in a new hideout.

Berti and Marchetti investigate the murder of Sarah, an irreproachable thirty-year-old secretary of an important financial broker. Her mother Daniela, worried about the girl's silence, finds her body, hermetically sealed in the closet of her house. Commissioner Fontana takes care of the difficult case (the murderer seems to have left no trace), also committing himself to mending the relationship with Nina.

Lorenzo, director of a drug rehabilitation center, asks for the help of Agent Valli to discreetly solve a crime that took place in the center: a former heroin addict now a night watchman was found dead in the warehouse. Irene is worried because her sister Valeria, Stefano's mother who has not yet managed to detox, also lives in the farmhouse and she fears that she may be implicated in the affair.

A criminal gunsmith is found brutally murdered in the back room of his front shop. The agents of the 10th Tuscolano investigate and a neighbor recognizes Petrocchi from the signs, an elderly thief expert in safes, now on semi-liberty. The man denies being in the business but a nasty surprise awaits him.

Following the attack on Commissioner Fontana by the fugitive Morace, archivist Parmesan risks his life due to a heart attack. Agents Valli and Gori investigate the death of a Nigerian prostitute who was trying to get out of the business, while Raffaele and Luca, struggling with the theft of a special ink for printing banknotes, make an unpleasant discovery about Giorgio, Anna's new boyfriend.

Among the documents of the murdered fixer, Commissioner Fontana, thanks to Nina's collaboration, finds evidence of a horrendous crime that allows the arrest of Neri Giorgio. But at the moment of the arrest the boss feels ill and Benvenuto is forced to follow him in an ambulance. In the meantime Raffaele investigates the attempted suicide of Marinella and Maurizio, a couple saved by their fourteen-year-old son Silvio. Agent Marchetti suspects a story of usury, which he experienced firsthand, and risks a lot with unorthodox procedures in order to frame the person responsible.

Rosanna is raped in her own home by a masked man who seems to have left no traces: the young woman, shocked, only remembers that the attacker had a slight limp. Anna and Irene investigate the case which presents analogies with other unsolved rapes. Agent Guerra and Ingargiola are instead tasked with tracking down a prisoner who escaped, strange coincidence, on the same day that the theft of a precious piano is reported.

Anna and Irene are in a club where a drunk woman seems to need their help. The two officers accompany Gabriella home where they discover the lifeless body of fourteen-year-old Enrico, the autistic son of the woman, who is immediately arrested. Ingargiola and Vittoria are instead on the trail of a famous hypnotist who pushes his victims to hand over their savings. Fontana organizes Nina's transfer to the prison where her father is incarcerated: Neri has asked for an interview with the girl who immediately accepted.

A beautiful Albanian girl is kidnapped by a shady thug but manages to call the X Tuscolano asking for help. Ugo records her call which allows to trace the place of the phone call and her identity: her mother confirms that the voice is that of Elena, who has just arrived in Italy with the dream of becoming an actress.

Prosecutor Corradi decides to entrust Nina's safety exclusively to Major Patrizi. But Commissioner Fontana suspects that the latter is conniving with the Neri clan to eliminate the young woman. These are the worst hours for Fontana who sees her young friend completely exposed.

Prosecutor Corradi decides to entrust Nina's safety exclusively to Major Patrizi. But Commissioner Fontana suspects that the latter is conniving with the Neri clan to eliminate the young woman. These are the worst hours for Fontana who sees her young friend completely exposed. Irene and Anna are also in crisis because the case of a homeless man who died during the night seems to ambiguously involve the son of their colleague Vittoria, the high school student Francesco.

Nina is operated on after the terrible fall from the terrace of the building where she was hiding. Marcello, his wife Cristina, Matteo and all the agents of the X Tuscolano are close to the brave girl who dared to challenge her father and the clan he heads. In the meantime Corradi and the guard agent, Martino, are interrogated at the precinct by Benvenuto: the two claim that Nina, depressed by the long limitation of her freedom, attempted suicide.

The agents of the X Tuscolano deal with the attempted suicide of Milena, a ten-year-old Ukrainian girl temporarily fostered by an Italian couple who adore her. The judge, however, is adamant and orders that the little girl return to her hometown immediately, despite Milena's claims that they mistreat her in the orphanage. The story takes a dramatic turn as Fontana's lucidity is put to the test by a man who wants to force his partner to keep the child she is expecting, going so far as to commit a sensational act.

Alessandro Berti is the district manager after Fontana's departure. He coordinates the service of Anna and Irene, responsible for the transfer of a batch of ancient pottery of immense value. Raffaele, who has never given up his suspicions about Gori's boyfriend, informs Luca of the progress made in the investigations on Giorgio Potenza and on a new lead, without even suspecting that the story is about to take a very dangerous turn.

Anna throws herself into work to forget the disappointment she has just suffered: with Raffaele she investigates the disappearance of twenty-year-old Marika, reported by her friend Pamela. Berti asks Valli for help in the Neri affair: the boss has in fact obtained house arrest. Fontana is working through his grief where his story began, in Calabria: he visits the grave of his best agent, Dante Santagata, Nina's boyfriend who was killed by Neri. And he has a strange encounter, which perhaps will give him the strength to react.

Berti and Boni of the forensic team investigate the murder of a Senegalese man outside the nightclub where the immigrant worked as a waiter. Fontana returns from his trip to Calabria and immediately confronts Neri, awaiting the trial that, according to his lawyer Mantovani, will clear him of all charges. Marcello promises the boss that his friend Nina will have justice and immediately returns to duty at the X Tuscolano, welcomed with joy by all the officers.

Marchetti is forced to confront his painful past, as the investigation into the murder of the owner of an arcade leads Anna to suspect Massimo Sepe, son of the criminal killed by Raffaele years before and now an employee of the victim. In the meantime, Cristina, wife of Commissioner Fontana, discovers that Matteo, at school, has received an explicit threat to their safety from two strangers.

In the meantime, Cristina, wife of Commissioner Fontana, discovers that Matteo, at school, has received an explicit threat to their safety from two strangers. Marcello has the family placed under guard and with Irene and Alessandro sets a trap for Morace.

While all the agents of the X Tuscolano are looking for Commissioner Fontana, who disappeared in Morace's van, Berti and Ia Valli are called by Tiziana. The coroner of the X Tuscolano has recognized the body of Veronica Todeschi, sister of her friend Franca and asks for their help on the difficult case. The girl, very beautiful, seems to have been thrown off the cliff overlooking the place where the body was found. But who could have had it in for a student with an apparently irreproachable life?

Valli and Berti try to gather as much evidence as possible against Neri before the final trial, almost a farce without Nina's testimony. Anna, Luca and Raffaele instead investigate the death of Don Michele Martinelli, stabbed in his own sacristy. The parish priest, highly esteemed by the community of believers, however seems to hide a terrible secret, perhaps the cause of his murder.

What happened to the drug shipment that Neri and Mantovani were expecting from South America? Finding it is the only hope for Commissioner Fontana, since, as feared, without Nina's testimony the Court of Assizes acquits the 'ndrangheta boss of all charges. Neri is free again and all the agents of the X Tuscolano are engaged in a race against time to find the drugs before they are refined and put on the market. Fontana accepts the challenge, putting the safety of his loved ones, his wife Cristina and his son Matteo, at risk.

Fontana wakes up in the hospital, in the hardest moment of his career: he is safe but does not remember anything about the car accident and the tragedy that occurred. The agents of the X Tuscolano will have to prove the innocence of the commissioner and fight with their own doubts, while Irene and Alessandro try to protect Stefano who, in the company of his father, is risking his life because of him.

It's Luca Benvenuto's first day as coordinator of the 10th Tuscolano. The case is an assault on a couple. Meanwhile, Marco, Elena Argenti's brother, the new inspector of the district, finds himself in trouble due to gambling debts with the boss Luciano Gerace.

Irene is taken to the hospital in very serious conditions and the entire district gathers around her and Alessandro. Meanwhile, Luca organizes the search for the robbers. Raffaele and Elena, instead, must investigate the death of a boy, Antonio Servidei, whose body was found on a construction site.

Little Simone Fioroni is kidnapped from his mother Matilde's car. Meanwhile Alessandro continues his investigations into the robbery gang; following the trail of the car used by the robbers, which had been rigged, he arrives at a mechanic who is a potential accomplice of the criminals; to make him confess he risks going over the limit and is stopped by Luca, with whom he ends up arguing.

Alberta Tizzani was attacked in her home and helped by her neighbor Marcello; it is he who suggests to the men of the X° Tuscolano that, although the woman claims it was a theft, the culprit could be Cristiano, her husband, a domineering and violent man. Cristiano, however, denies everything.

A woman accuses her ex-husband of beating and kidnapping her, but he denies it and for our men, faced with a web of hatred and lies, it becomes difficult to understand the truth. On the investigation side of the robbery gang, a glimmer of hope seems to open up: it seems that the gang will strike again soon. Our men prepare to surprise them on the spot.

After the disappointment of the failed operation to arrest the members of the robbery gang, a strange phone call takes our heroes to the scene of a murder. The victim is an acrobat thief who may have stepped on someone's toes. But by investigating the man's movements, another truth will emerge. Meanwhile, Alessandro, thanks to a case he stumbles upon, finally faces his grief and returns to Irene's grave.

The men of the 10th Tuscolano are on the trail of the Talicam technician who passed the gang the codes needed to carry out the robberies. In the meantime, a murder is committed in a call center and suspicion falls on one of the employees.

After the setback caused by the death of Talicam technician Ottavio Rinaldi, the men of the X° Tuscolano manage to trace a clandestine gambling den run by Camorrista Luciano Gerace.

While Luca follows the trail of Luciano Gerace's (Dante Palladino) Camorra clan, Alessandro, trusting his police instinct, decides to "hook up" Melissa. Meanwhile, the rest of the X° Tuscolano deals with the murder of a mother, in which the main suspect is the woman's stepson. The case is complicated by the fact that the only witness is the lady's biological son, an autistic boy with whom no one seems able to communicate.

While Luca perseveres on the trail of the Camorra, Alessandro continues to see Melissa in secret, putting his life at risk. The case of the episode instead concerns the alleged suicide of a woman no longer young suffering from cancer, whose "last journey" hides a much more disturbing truth.

After risking being killed, Alessandro involves his companions in the search for Melissa, which, in a crescendo of tension, ends with our friends falling into a trap set by the Flaviano brothers. During the episode, the murder of a construction site foreman is also investigated: what at first glance seems to be a simple case of revenge linked to accidental deaths at work, actually hides a much more complex scenario.

Having miraculously escaped the Flaviano attack, our heroes receive a tip from Melissa that leads to the discovery of the weapons used in the robbery in a warehouse in Gerace. The investigations therefore seem to be concluded, but Luca and his team still have doubts. Meanwhile, an investigation is being carried out into the murder of a pharmaceutical representative struggling with a financial hole in his company and two women, his current wife and his ex, who hate each other to death.

The men of the 10th Tuscolano are busy solving a case involving a young non-EU citizen. Thanks also to the help of Vittoria our men discover that Samira, the young woman, is the nanny of a family blackmailed by some loan sharks.

Anna and Raffaele deal with a case involving Alessia, raped a year earlier and now accused of taking revenge on the culprit.

Melissa's death triggers a deep crisis in the District. Especially in Alessandro, who feels responsible. After solving a mysterious murder case in which a fortune teller was the victim, however, news arrives that Melissa did not commit suicide: perhaps there is a clue to start again.

While Giulio Flaviano suffers from withdrawal, our heroes discover that the morphine used by Irene's killers is purchased thanks to a stolen prescription pad, therefore recognizable: they just have to wait for them to go back to do the "shopping". In the meantime, they have to solve the case of a girl who disappeared 12 years earlier and was found in a coma in a wood.
