When psychology lecturer and psychic mediums specialist Robert Bridge takes his students to a clairvoyance evening, he meets troubled psychic Alison Mundy. Sceptical about her abilities, Robert decides to study Alison and contemplates writing a book about her after sitting in on one of her readings. But he is completely thrown when Alison claims to see the spirit of his dead son Josh.

Alison thinks that she is being haunted by the victims of the train crash which nearly killed her six years before. But she soon finds out that she is being followed by the survivors of the disaster, who want her to help them communicate with their lost loved ones. Robert and she come into contact with the afterlife in a way that will change their lives for ever.

Alison Mundy is still recovering from the traumatic seance that put her in a coma. She realises that she has dedicated her life to helping the spirits and when she sees one on the roadside, she is determined to find out what has happened. Before long she is entangled in a story that involves a car crash and some friends. But this time, she won't be able to help everyone...

When a teenager, who has been haunted by a young boy, claims a psychic he visits is an impostor, Alison tries to sort things out. However, she find that on this occasion, she can't contact the spirit world. Robert still hasn't told Alison of his tumour, but will he ever get the chance, before it's too late?

With Robert in a coma at the hospital, Alison rushes to his bedside, finding Jude there, who is less than happy to see her. Whilst in the hospital, waiting, the psychic witnesses a strange nurse wandering the corridors. This is confirmed by many of the workers, who have heard rumours about this unusual being. Why is she there - and does she mean the end for Robert?
