Four months after surviving a car crash that killed her husband, pregnant Sarah is alone and depressed on Christmas Eve, and due to have her baby the next day. Violent protests are happening in the streets, but she doesn’t want to be with anyone, despite her mother and boss Jean-Pierre offering her opportunities to come to parties, or keep her company. So Sarah settles in for a night of knitting, when suddenly… a knock on the door. Who is it? The woman behind the door just wants to use a phone, but she also knows Sarah’s name. And what begins as an indoor-outdoor game of cat and mouse turns into a cascading symphony of violence, with nothing less than the fate of Sarah’s baby hanging in the balance.
