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.
