Parisian Commissioner Henri DuPont is forced to reopen the case of Sophie Legrand, dubbed the "Black Widow" by the press. Their meeting in a luxurious hotel escalates into a dangerous psychological duel. Sophie appears sometimes as a fragile victim, sometimes as a cold and calculating woman. Driven by a thirst for justice, DuPont is drawn into a tangled relationship where threads of truth and lies form a deadly web. His investigation leads him to the private "Sainte-Anne" sanatorium, where he encounters the mysterious "Rule of Four" and realizes he has become a pawn in a game where good and evil lose all meaning.
