Martin (Aidan McArdle - Perfect Day) is worried about his baby son. While his wife Ruth (Zoe Telford - Absolute Power) is out at work, Martin stays at home looking after him. But he has started to hear a disembodied voice over the baby monitor, a sinister presence whispering nursery rhymes to his child. Risking his wife's ridicule, Martin contacts Alison for help. She identifies a malign spirit, but when Ruth finds out a medium has been in her home she is furious. Ignoring Alison's advice to take her baby away from the house, Ruth is convinced that both Alison and her husband are mad. Martin starts to crack under the strain, leaving his baby ever more vulnerable. Back at Alison's house, Robert witnesses her increasingly odd behaviour which is beginning to border on the obsessional. When he questions her, Alison reluctantly reveals that she is being haunted by the spirit of her mother who died in a psychiatric institution when she was a child. Robert wants to help Alison, but he has mounting problems of his own. He and his ex-wife Jude (Anna Wilson-Jones - Monarch of the Glen) spent the night together for the first time in several years and he realises his feelings towards her have never gone away. Just as he is wondering how to handle this unexpected development, his life is thrown into chaos. He learns that he has an inoperable brain tumour and may have only weeks left to live.
