S1, E1: Modern version of Andrea Newman's 1976 taboo-busting psychological drama, reworked by acclaimed writer Guy Andrews. This new three-part series explores the consequences of a father's obsessive love for his daughter and how long-buried secrets come back to haunt their lives. Peter Manson's apparently successful life and career are turned upside down when his daughter Prue reveals that she is pregnant by her teacher Gavin Sorenson. The future of the family is threatened when it becomes clear that Peter cannot rid himself of the suspicion that Gavin's interest in Prue is part of a personal vendetta and quest for revenge. But are Peter's feeling just fatherly concern or has his love for his daughter become an obsession?
