Matteo, a forty-year-old cartoonist, divides his time between work and family and nurtures the dream of publishing his own comic book starring Solo Valentine, a selfish superhero who uses his powers only for himself. He is married to Paola, a successful writer. A pleasant family picture, with three daughters, Virginia (9), Ginevra (6), Melania (2), and two dogs, is thrown into crisis when Sara, an old acquaintance of Matteo's, reappears with an offer he cannot refuse: to publish his comic book on condition that he moves to Paris.

After the news of the death of Don Dino, who was transferred to Trentino, Donato leaves to attend the funeral. When he arrives at his destination, he discovers that he has been appointed his deputy in the parish.

Donato, a scoundrel music manager, to escape the two henchmen of a boss who, due to his inefficiency, has caused him to lose a lot of money, taking advantage of a letter from his uncle the bishop, introduces himself to the parish priest of a village church, Don Dino, dressed as a priest, and pretends to have been sent there by the bishop as assistant parish priest. Don Dino's church is always empty. In fact, the town's faithful frequent the new church, run by Don Gabriele, a pimp priest who knows how to deal with people. Donato's arrival initially seems like the final blow for Don Dino's church: Donato doesn't know where to start a mass, he has never confessed or married anyone, the mere idea of ​​performing an extreme unction scares him. Don Dino begins to argue with Donato: he seems anything but a priest. But little by little, Don Donato's extravagant ways, his open-mindedness as a "sinner", his mentality as a rock priest, begin to attract the faithful.
