Disgraced former detective Mike Humber gets off a train in the bleak autumn countryside, his mind haunted by a dark past.
A new job awaits. Huntington House needs a live-in security guard to prevent access during an inheritance dispute.
This is exactly what Mike needs: a new start in a new place and a chance to turn things around.
It all seems perfect, especially when he meets Tessa.
But Huntington House holds dark secrets. Bumps in the night. Flickering lights. Music playing from somewhere.
Mike's mind starts to unravel as he questions his sanity in the dark, claustrophobic corridors and rooms.
Something isn't right.
There is someone else in the house.
The pressure grows as the people around Mike get pulled into a web of lies and manipulation, forcing him to take action before it's too late.
