Someone knows everything you did… and they’re watching you…

Daniel is living the fantasy with a devoted wife, ideal work and adorable young child. Until out of nowhere, his wife accuses him of having an affair and stabs him in a frenzied attack with a kitchen knife. As his wife is sectioned in a psychiatric ward, Daniel profits home from intensive care to discover his precious world is inexorably falling apart:

Who is prowling around his house?

Why is someone mailing threatening postcards?

And who’s his son speaking with in the deceased of night?

As Daniel efforts to put his life back again jointly, a merciless force just out of reach is unraveling it, bit by bit, until Daniel is plunged into his worst nightmare.
