An eight-year-old girl goes missing and her distraught parents make an emotional televised appeal. The next day, when Alison says she has seen the child's ghost in the supermarket, the police are deeply suspicious - then they discover a drowned body.

On the first day of her new job at an old people's home, Alison finds a photo of Robert's dead son Josh, belonging to his mother, Jenny, and realises that Josh steered her towards the job in another attempt to make some kind of emotional contact with his father. Alison befriends fellow nurse Connor, who is being tormented by the ghost of a former patient, who jumped to her death from a window because he wouldn't help her die peacefully.
