Post-graduate student Gemma is still mourning her friend Beth who died when an intruder broke into their flat. She asks Alison to help her talk to her friend, but after Alison makes contact a more sinister and unexpected figure begins to haunt Gemma - the ghost of Beth's attacker. As the spirit pursues Gemma, Alison tries to help. But Gemma's behaviour grows more and more disturbed as she develops a bizarrely sexual relationship with the spirit, and Alison begins to suspect that Gemma knows more about her pursuer than she is letting on. Robert's illness has forced him to focus on how best to spend the time he has left. He is determined to help Alison, who is starting to exhibit the same irrational behaviour that her mother did at the height of her madness. But when he tries to confront Alison she shuts him out, refusing to reveal any details of her mother's past. Robert cannot bring himself to tell Alison about his condition, but he feels he can no longer hide the truth from Jude. He has no idea how she will react when she finds out what she thought was the start of a new relationship is really the beginning of the end.
