Stéphane Leroy, a wealthy industrialist, has recently married Gabrielle. The treacherous Gabrielle can only rejoice: Stéphane has slipped into a coma, and she is about to take over his empire and his immense fortune. But some unexpected news brings her enthusiasm to a screeching halt: her husband has a daughter, Blanche, who is said to be living in seclusion in a girls' boarding school and about to turn 18.
