French horror about a couple who have to fight for their lives when an assault on their home turns deadly. The story opens with the murder of two Romanians, a woman and her young daughter, who crash their car along a rural road and are promptly butchered by a shadowy figure. Meanwhile, in Bucharest, schoolteacher Clementine (Olivia Bonamy) climbs into her car and drives to the isolated mansion that she inhabits with partner Lucas (Michael Cohen), not far from the site of the murders. Soon the couple overhears someone stealing their car, but a call to the police accomplishes little. The lovers gradually realise that an outsider is attempting to break into the house with homicidal intent.
