In Caracalla, two Roman townsfolk, Scintillone and Ruggeretto, let two young prostitutes, Anna and Supplizia, get into the car, who were arguing over "area" reasons, in order to go unnoticed by the police as they try to place some stolen guns.

Returning to Rome, the three couples stop along the country road and withdraw to "celebrate", but then the boys, once the fun is over, run away leaving the girls on foot and begin to argue about the sharing of money: that's when they realize that Anna, as suspicious as her colleagues, has stolen Scintillone's wallet.

Then, seeing a nice unattended car, they try to steal a radio left on the seat, but they are surprised by the owners, three guys from Roma well: Achille, known as Moretto, Pepito and a third companion.

A fight begins, immediately interrupted by the arrival of the police, and the three boys take away the three townspeople apparently to get them out of trouble, but in fact to go to an isolated place where they can get satisfaction.

After a passage in a bar, the six pass through the Caracalla area again where they meet Nicoletta: having found that she does not have the money and that Anna and Supplizia have abandoned her, they let off steam by throwing waste and water from certain vases on her flowers.

The latter seems to show a certain sexual ambiguity, only hinted at previously in the caresses made to a boy in the meadow where the group had to fight, while Ruggero makes the "acquaintance" of Laura, a pretty blonde who at first passes herself off as the sister of Achille and then reveals that he works in the service of the rich home.
