Synopsis: (NO SPOILERS)
The story concerns police detective Mackenzie Stone whose wife disappeared a few years ago - and he who still recovering from the incident - experiencing weird dreams and the like. At the same time we are introduced to another man - John Dean, who is suffering from total amnesia, meaning that he remembers nothing of his past life before he turned up in hospital 5 years ago.
Mackenzie Stone, played by John Hannah becomes convinced that he knows who John Dean really is, that he is a man who dissapeared a few months before John Dean appeared - and that he murdered his family before hand to claim the insurance money. However, it starts to become apparant that DS Stone may well have killed his own wife...
