Carlo asks approval to his mother Lina to perform this new job of his, and he obtains it after some initial hostility from her.

At the same time Carlo falls in love with Maritza, a new girl in town (freely based on Bocca di Rosa, the protagonist of De André's eponymous song from 1967).

The pair find themselves involved in a big heist on account of local criminal boss Bernard.

In a surprise plot twist, it is revealed that the money was stolen by Salvatore, who also took the chance to kill his twin brother - because of whom he had unjustly been jailed for five years.

However, while escaping on a train, Salvatore has a change of heart and confesses his theft and his murder to a man whom he erroneously believes to be a priest, but who is actually a hitman working for Bernard.
