The story is about a youth named Massimo Monaldi, who, living in Rome, is a part-time college student who has some involvement in the protests that occur at his university. Massimo is also involved with drugs and he sometimes steals to make a living and support his habit (the theft of a tobacco box is very important to the story).

Both families don't approve of their relationship with Massimo.
