Early 1970s British horror. Susan George stars as Amanda, a young babysitter who arrives at the isolated home of Helen and Jim Lloyd (Honor Blackman and George Cole) to look after their young son, Tara (Tara Collinson), for the evening. Shortly after the couple leaves, a series of frightening events set Amanda's nerves on edge - but the real terror begins when the child's biological father (Ian Bannen) turns up at the house after escaping from a nearby lunatic asylum. Dennis Waterman co-stars.
