A successful lawyer jeopardizes her career and threatens to tear her family apart after engaging in an affair with her teenage stepson.
Anne (Trine Dyrholm) and her husband Peter (Magnus Krepper) are an affluent middle-class couple living with their two young daughters on the edge of a forest just outside Copenhagen. She's a partner at a law firm specialising in defending victims of sexual assault and domestic violence, whilst he's a top surgeon. Their life is uneventful but happy. Things change, however, when Gustav (Gustav Lindh), Peter's recalcitrant teenage son from his first marriage, arrives to stay with them, having been expelled from his Swedish school. Although initially, Anne is far from enthused about his sullen presence, over time, he awakens something in her, and she seduces him, with the duo subsequently embarking on a dangerous affair.
