Una notte di due balordi, Scintillone e Ruggero, a cui si aggiunge in seguito un terzo, Bellabella, che dopo un furto vengono a loro volta derubati. Tentano poi di rubare un'apparecchio fotografico da una macchina; sorpresi dal proprietario, Achille, ci fanno amicizia e si recano a casa sua. Qua rubano nuovamente, duecentomila lire, e scappano. Ma litigano per il bottino. Cos8 tra liti, arresti e donne continua la notte finchF all'alba Ruggeretto si ritrova con mille lire e la nausea.

Ruggeretto, Scintillone, and Bella-Bella, three indolent young cynics, steal some rifles and pick up two prostitutes on their way to a "fence" on the outskirts of Rome. During the transaction, they pick up a third prostitute who wants a ride back to the city. En route, the youths stop the car, take the women into the woods for the afternoon, and then leave without paying them. They soon discover, however, that one of the women has stolen all their money. Back in Rome, the companions attempt to steal a movie camera from an automobile and get into a brawl with its occupants, three wealthy homosexuals who then treat them to an evening of drinking. At the apartment of one of their newfound friends, Achille, the inquisitive Ruggeretto wanders into a bedroom and finds Laura. He seduces her, although he is unsure whether she is Achille's sister or the maid. Bella-Bella then steals his host's wallet, and the three hoodlums race from the apartment. As Bella-Bella and Ruggeretto argue over the money, Scintillone picks up the wallet and skulks off. He meets an old flame, Rossana, and promises her a night on the town, but he creates a disturbance at a posh restaurant and is led away to jail. Ruggeretto arrives on the scene, grabs the wallet, and takes Rossana to the most expensive club in Rome. When morning comes, he crumples his last bill and tosses it over the side of a bridge.
