Fed up with her cheating husband, Paris art restorer Louise, 45, secretly flies to Corsica with plane tickets that he had purchased for himself and his mistress. Once there, in full revenge mode, she spends a frenzied night with a seductive man named Florent Lucciani. Upon waking the next morning, her brain foggy, she finds traces of cocaine in the hotel room. Then she spots the dead body of Florent and panics. When local inspectors suspect she may have had something to do with his death, she’s temporarily saved by Florent's widowed mother, who mistakes her for the daughter-in-law she’s always dreamed of having.
