To postpone the deadline for some very tough exams, the students of Class 3C invent a visit from an Oxford professor—actually a former student, a chronic repeater like Chicco—persuading the principal to fund a performance of Shakespeare's most famous works. Chicco plays Iago, Massimo plays Cassio, Sharon is Ophelia, and Benedetta is, of course, the occasional director. In Class 3C's unique "interpretation," however, the English playwright's works become ignoble farces, with only Bruno escaping, forced to play Othello, who on the day of the "premiere" (and final) performance achieves an unexpected personal success. But once the curtain falls, the story of the fake English professor comes to light. Tragic "reruns" are prepared for everyone.

The students of Class 3C have always been drawn to ambitious artistic endeavors. After their school play, this year they even decided to make a film. It's a horror film titled "Quella scuola accanto al cimitero," directed by Benedetta and starring poor Bruno, reluctantly, in the demanding role of a paranormal being. Some bitter disagreements with producer Zampetti, however, will transform the film into a long and terrifying commercial for cured meats and cotechino.

This year, as tradition dictates, the legendary football match between the 3rd C and 3rd F teams is being celebrated. It's a real derby, one that promises to be fierce and fierce, given the long-standing rivalry between the two classes. Our players are preparing diligently for the big match. Their coach is Ciro, Bruno's stationer, who certainly isn't the most reliable; their sponsor is, needless to say, the Zampetti salami company; and even a foreigner, Aziz, the sponsor's Somali waiter. The 3rd C team enters the derby as a clear underdog. But, as they say, the ball is in the air.

A mystery unfolds in class 3C. Many students' snacks mysteriously disappear from the classroom. Food thefts become increasingly frequent, and among the students, excitement gives way to nervousness and furious protests. Chicco decides to take matters into his own hands and, assisted by Bruno, launches into a thorough police investigation to track down the culprit. Naturally, Chicco and Bruno seem unlikely to be playing Sherlock Holmes and Dr. Watson.

Carnival is in full swing. For the occasion, the principal has organized a party in the school gym, attended by teachers and parents. It's clear that the students in Class 3C have other plans for their Carnival. On the evening of Fat Thursday, each of them, unbeknownst to their classmates, goes in costume to a large Brazilian party, hosted by Aziz and Puccio at Villa Zampetti. When the host unexpectedly returns, the disappointed students, victims of numerous misunderstandings, will be forced to quickly transfer the festive atmosphere of the Rio Carnival to the Sacchi household.

Our classmates become the protagonists of a thrilling news story. Two escapees, wanted throughout the city, find refuge in 3C and take the students hostage. Outside the high school, the police are mobilized, the parents are distraught, and Puccio's local TV station follows the drama live with bated breath. Only the students, overjoyed, enjoy the suspenseful day as a tempting diversion from school. The two convicts, in fact, prove completely harmless and are the only ones to experience truly terrifying hours, victims of the unbridled students of 3C.

There's war between the 3rd C and the 3rd F! Luckily, it's just a "soft" war with toy guns and tracer bullets, which leave only a red stain on the victims' uniforms. Nevertheless, General Chicco's soldiers take their little war very seriously. Boys and girls, mindful of so many war movies, transform themselves for the space of a weekend into tough guys, sharp strategists, and heroic kamikazes...plus one shirker: Bruno Sacchi.

Sometimes it's worth debunking the old cliché that perpetuates antagonism between students and teachers. That's what the students in Class 3C think when their distraught Italian teacher confesses he's in serious trouble due to an eviction order. To help him financially solve his problems, the students mutually make the fateful decision: "Let's go to work." They improvise, taking on the most diverse odd jobs: clerk, delivery driver, fortune teller.

Bruno Sacchi absolutely needs a car. It will save him from being constantly late for school and spending endless hours on the train. Unfortunately, Chicco and Puccio are his driving instructors. When he finally gets into his first car, a battered old dud given to him by the same old Ciro, the impact of city traffic is truly traumatic for Bruno.

The big moment has arrived. Our nine students from Class 3C are just one step away from the fateful finish line: their final exams. They all share a common feeling: fear, and are gripped by a sudden and frantic attachment to their studies. Sharing the anxiety and strain of those moments is an unusual private student: Commendatore Zampetti, forced by work to sit his final exams alongside the students from Class 3C.
