Julia goes to Caronte to ask him to defend Miguel, a teacher and colleague accused of murdering one of his pupils, Alicia, who he had a romantic relationship with. Caronte decides to accept the case even though Guillermo was Alicia’s friend and the young man is convinced Miguel is guilty, so he confronts Julia about it. Caronte finds evidence against Commissioner Paniagua.

Following the controversial Adeyemi case, Marta and Caronte defend some of the former’s acquaintances, Adela and Rosa, a mother and daughter accused of hiding a body in the wall of their nursery. The investigation will reveal dark secrets which even Adela herself was unaware of. After Natalia’s tragic loss, she decides to return home to Gijón to distance herself from all that’s happened.

With Caronte fully focused on unmasking Paniagua, Marta is alone working on a case very close to home. Her ex-boyfriend Mario could end up in jail for assaulting a co-worker under the influence of drugs. At the same time, Guillermo organises a big party at Caronte’s house where a mysterious man takes Caronte’s gun.
