In 1939, in a maternity ward, a young man visits his mistress who has just given birth to a little girl. He tells her that he is married and that for him the outcome of this adventure was not really planned. The mobilization separates them but the young man will end up divorcing and with the relentless help of a friend, will find his mistress and his child and will be able to marry her in spite of the chaos of the war.
In the 1880s, Georges Duroy, back from the Colonies, arrives in Paris with the firm intention of conquering the capital through his power of seduction, his selfishness and cynicism. Entering into journalism through the back door he will soon rise to the top with the support of several women: Madeleine Forestier, the wife of his journalist friend Charles; Clothilde de Marelle, his first mistress; Virginie Walter, the wife of a newspaper owner; Suzanne Walter, her daughter who eventually marries Duroy.
