Juliette Binoche is Sara, a presenter on a highbrow Paris radio talk show, who for 10 years has lived with Jean (played by the smoulderingly rumpled Vincent Lindon); a former sports star, who has served time in prison for an unspecified offence. Jean has a teen son, Marcus whose mother now lives abroad and who is being raised by Jean’s mother Nelly.

The third corner of the triangle is François, Sara’s ex-lover whom she left for Jean on a passionate impulse a decade ago.

A tense and erotic yarn that is simply tremendous.
