Push a red button on a little black box, get a million bucks cash. Just like that, all of Norma (Diaz) and Arthur Lewis's financial problems will be over.

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. 'Somebody pushing your buttons?' a woman asks.
