Having recovered from a shattering emotional breakdown, college professor Ben Marshall (Ed Stoppard) relocates to the countryside with his wife (Sophia Myles) and young son (Isaac Andrews), hoping for a fresh start. He has a teaching job lined up and a new home, Blackwood House to move into; things finally look to be going Ben's way. Until, that is, he starts to feel that something isn't quite right in the house. Finding himself plagued by ghostly visions, Ben discovers the house a dark secret and he becomes obsessed with uncovering the truth behind a disturbing local mystery that could put the lives of his family in danger. His investigation leads him to the sinister local gamekeeper Jack (Russell Tovey) and the ex-paratrooper vicar, Father Patrick (Paul Kaye). Trouble escalates when an old friend Dominic (Greg Wise) and his girlfriend (Joanna Vanderham) enter the frame.
