Zabette de Chauvalons leaves a convent in Brussels to join her father on the island of Martinique, escorted by Père Bénédict. In St. Pierre she finds that her father has died; his widow, who rules the island's French society, believes Zabette to be the child of a beautiful quadroon with whom Zabette's father left for France; when Zabette is sent to the mulatto quarter, Stéphane Séquineau is present and takes an interest in her. Destitute, Zabette is forced to auction off her Paris fashions, and though Quembo, a cunning quadroon, is the highest bidder, Stéphane outbids him at the last minute and professes his love, which she accepts, believing herself to be une fille de couleur; however, his older brother, Maurice, insinuating that a mixed marriage would ruin him, persuades her to desist.
