The film is set in Milan, where Susy and Angela meet in a club bathroom. There, they take possession of a ring forgotten by a lady. After going to movie, they meet Vito, a taxi-driver who promises to help them selling the ring. The search for a buyer begins at a fence's house and continues until a party at the house of Destino, a travesti, where a jeweler buys the ring at a fraudulent price that the trio are forced to pay. But, after going out and loading a "life boy" (ragazzo di vita[2]) in the car, they realize that the money is gone.
Despite this setback, the evening continues and, after a meeting with Marta and Davide, a rich vicious couple who involve them in erotic games, the two girls fight, to the disappointment of Susy who seems not to accept the greatest success of Angela with men. At this moment the three separate: Angela spends a disappointing night with Piero, a young boy met in the villa of the vicious couple, while Susy goes to the station to leave Milan. In the morning the two girls meet again and after confessing that Angela took the money that seemed to have disappeared and Susy managed to steal the ring from the jeweler, they become friends.
^ In Italy, the ragazzi di vita are unemployed boys who walk the sidewalks at night to wait for customers and who dream of a good life, but who most often end their lives sadly, in disease and drugs. See also the novelRagazzi di vita by Pier Paolo Pasolini.
