Synopsis
After their parents die in a road accident, a strongly moral young woman named Thérèse Voise leaves a convent shortly before taking her vows in order to care for her younger sister Denise and run the family stationery shop with her. Thérèse is very protective of Denise and becomes concerned when her sister strikes up an acquaintance with Max, a young amateur boxer and garage mechanic. Max is a self-centered, amoral drifter who is conducting numerous different relationships with girls at nightclubs. He is also pursuing Irène Faugeret, a wealthy married woman, managing to get employment as her chauffeur and become her lover. Max strikes up a friendship of sorts with Biquet, a bellhop at the Hôtel Carlton who acts as Max's eyes and ears, especially as concerns Madame Faugeret.

Denise is attracted to Max, but after a chance meeting at the hotel he sexually assaults her. A distraught Denise attempts to drown herself, and is only narrowly saved from suicide. After she has recovered, Thérèse blackmails Max into getting engaged to Denise by threatening to reveal the circumstances to the police who are already investigating Max for the death in an automobile accident of Irène, his wealthy lover. Max was responsible for Irène Faugeret's death as he had loosened three screws on her car's steering column. Max did not expect her to use the car the night of the fatal accident. He expected Biquet would use it instead, part of their scheme to steal Irène's money and then flee to Tangiers to start a new life. Max was hoping to double-cross Biquet. Instead, he caused Irène Faugeret's death.

Denise is delighted and optimistic about the future. However, Thérèse remains contemptuous of her future brother-in-law.

Max tries to persuade Thérèse that he has fallen in love with her and attempts to seduce her. She rejects his advances, but it remains unclear to what extent she is attracted to him. Max tries to persuade her to run away with him to Tangiers where they can start a new life together. The sincerity of his actions remains in doubt even up to the moment when, having absconded with Denise's dowry and Thérèse's passport, he is killed by a train while trying to board it in order to complete his rendezvous with Thérèse. Philosophically accepting this turn of events, she returns to her convent to become a nun.
