Someone knows what you did... and they're watching you...

Daniel is living the dream with a devoted wife, perfect job and adorable toddler. Until out of the blue, 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 returns home from intensive care to find his precious world is inexorably falling apart: Who is prowling around his house? Why is someone sending threatening postcards? And who is his son talking to in the dead of night? As Daniel attempts to put his life back together, a merciless force just out of reach is unraveling it, bit by bit, until Daniel is plunged into his worst nightmare.
