All four episodes of the Channel 4 psychological drama about a troubled teenager. On the surface, 16-year-old Sam Woodford (Jack Rowan) is a well-adjusted, normal teenager who enjoys sports, gets by at school, has a good relationship with his mother Jenny (Romola Garai) and takes good care of patients in a geriatric ward where he works part-time. However, he puts in a lot of practice behind closed doors to maintain his charming facade for reasons which remain unclear. As he tries to get closer to the new girl at school, Chrissy (Lara Peake), it's not long before Sam's psychopathic tendencies reveal themselves while Jenny tries her best to protect both her son and herself from a violent figure from her past.

All four episodes from the fifth series of the ITV crime drama, adapted from the novels by Agatha Christie. Julia McKenzie stars as Miss Marple, the elderly woman who investigates crime in her local village. Episodes comprise: 'The Pale Horse', 'The Secret of Chimneys', 'The Blue Geranium' and 'The Mirror Crack'd from Side to Side'.
