Push a red button on a little black box, get a million bucks cash. But there's a catch: Someone, somewhere - someone they don't know - will die. Cameron Diaz and James Marsden play a couple confronted by agonizing temptation yet unaware they're already part of an orchestrated an - for them and us - mind-blowing chain of events. Frank Langella also stars in this gripping sci-fi mystery thriller from director Richard Kelly (Donnie Darko) and a short story by Richard Matheson (I Am Legend).
