There's a stranger in your house. And he knows your biggest secret.
When Kimber Hannon returns home from a work trip, she's ready to kick back and relax on the sofa. But on reaching the front door, she is shocked to discover that her key no longer works and there's a man in the bedroom window. Kimber calls the police, but the intruder tells them he's renting the house. Her neighbour corroborates his story and it is Kimber who is forced to leave. But before she does, the stranger whispers 'I was there. I saw what you did.' These words reveal a connection to Kimber's distant past, and dark secrets she'd long ago left buried.
Her trespasser isn't after anything as simple as her money or her home. He wants to move into her carefully orchestrated life - and destroy it.
