Late one night a man walks into the luxurious home of disgraced banker Harry McNamara and his wife Julie. The man launches an unspeakably brutal attack on Harry as a horror-struck Julie watches, frozen by fear. It looks like Harry's many sins - corruption, greed, betrayal - have finally caught up with him.

An hour later the intruder, JP Carney, hands himself in, confessing to the assault. The police have a victim, a suspect in custody and an eye-witness account, but Julie remains troubled.

Has Carney's surrender really been driven by a guilty conscience or is this confession the first calculated move in a deadly game?
