Trapped in a marriage with the cold-hearted Robert, Catherine has long been determined to leave. The situation reaches breaking point when Robert returns from a business trip and catches her cheating. For Catherine, this finally marks the beginning of the end, but Robert refuses to let her go. Everything changes when Robert has a car accident in which he and their daughter Sarah are badly injured. Little does he know that this is where his story will intertwine with that of Viktor, a mentally retarded boy whose abusive mother dies in the same car accident. For some time, Viktor had wanted to break out from under her tyranny and go his own way but couldn't stand up to her. In Robert's wallet, Viktor finds a photograph of Catherine, and his sick mind hatches a mad plan: Catherine should pay for his mother's death.
