John Turturro is superb as Harry Caine, an everyman Shopping Mall Security Guard who is desperately searching for a reason for the murder of his wife. He spends his nights watching CCTV footage to see if there is a face that might give him a clue. His walls are plastered with 'suspects' and when he closes in on the potential killer, his world is turned upside down yet again. What does he want, revenge? Closure?
