A pair of cousins share a flat, but animosity begins to build between the two when a woman gets involved.

Charles is a young provincial coming up to Paris to study law. He shares his cousin Paul's flat. Paul is a kind of decadent boy, a disillusioned pleasure-seeker, always dragging along with other idles, while Charles is a plodding, naive and honest man. He fell in love with Florence, one of Paul's acquaintances. But how will Paul react to that attempt to build a real love relationship ? One of the major New Wave films.—Yepok

The naive mama's boy Charles moves to Paris to live with his debauched bon-vivant cousin Paul Thomas in his apartment. He meets Paul's friend, the pervert pimp Jean "Clovis", who is older than them. Paul studies hard and writes daily to his mother while Paul gives frequent parties and neither studies nor goes to lectures. When Charles meets Paul's friend, the gorgeous and promiscuous Florence, he falls in love with her. They talk later through telephone and Florence understands the invitation of Charlie to meet her wrongly and arrives earlier at his apartment. She meets the cynical Paul and Clovis that tell her that she is a slut and will cheat Charlie when she becomes bored with him, and she ends having sex with Paul. Florence moves to the apartment to live with Paul, disturbing the attention of Charlie in his studies. When the final exams come, there is a tragedy.—Claudio Carvalho, Rio de Janeiro, Brazil

Charles, a young provincial student, arrives in Paris to take a room at his cousin Paul's. Paul, also a student, seems only to be interested in hanging out and partying. Charles falls in love with Florence, whom he meets at Paul's favorite hang-out. Clovis, a trickster friend of Paul's, who is always turning up at the flat, has a hand in manipulating the action. An early and highly regarded work by Chabrol.—Chridman
