Rome, 1990. The night Italy's national football team is eliminated from the World Cup by Argentina on penalty kicks, a well-known film producer is found dead in the Tiber river. The main suspects for the murder are three young aspiring screenwriters, who–promptly taken to the police–start to tell their version of the story.

Valeria, young secretary of a producer, lives with an eccentric mother and secretly writes for a successful screenwriter, Alessandro. One day, she receives an unusual present from a stranger: it’s the plot of a movie about the mysterious but really-happened theft of a famous Caravaggio’s painting.
