Cattion d'Urville takes in a gypsy, Sarah, and her granddaughter Miarka, in an outbuilding of her chateau. Miarka, while growing up, attracts the attention of Luigi, Cattion's nephew who, little by little, falls in love with her. Sarah raised her daughter in the tradition of gypsies who curse anyone who marries a man who is not a gypsy. Miarka ends up loving Luigi and he wants to marry her. The law of race opposes it. Fortunately, a well-conducted genealogical investigation will discover that Luigi is of the gypsy race. They will marry.
