Le marquis de Condottier, homme vain et sans scrupule, est l'amant de la femme de Jacques Herbelin, Louise, mais il séduit en plus la fille de celle-ci, Cécile. Sa maîtresse se plaint à son mari qui devenu furieux tue le marquis en le noyant. Finalement, la police ferme les yeux, Cécile se marie et Louise Herbelin se repent.

Jacques Herbelin is the faithful husband of Louise and the proud father of Cécile, a kind little girl. But Louise does not reciprocate her husband's affection and prefers to cheat on him in the arms of Marquis de Condottier. The latter is a sinister character who, not satisfied with being Herbelin's wife's lover, sets his heart on their daughter, who has now become a pretty young lady. Jacques can't take it anymore.
