When Stéphane (Laure Calamy of Call My Agent!, Full Time) gets in touch with wealthy Serge (Jacques Weber), announcing that she is his long-abandoned daughter, his immediate family is none too thrilled. As Stéphane embarks on an extended visit in hopes of getting to know Serge, she also becomes entangled with the hostile women who share a tense existence in his beautifully appointed mansion by the sea: the restaurateur’s wife (Dominique Blanc), his other daughter (Doria Tillier), a rebellious granddaughter (Céleste Brunnquell), and a strangely off-putting housemaid, all of whom are clearly unsettled by the arrival of Serge’s newly announced heir. But Stéphane is a confident liar with secrets of her own, which writer-director Sébastien Marnier teases out with cool assurance in this wildly entertaining thriller that will keep you guessing all the way to the end.
