After Ben gazes into the mirrors and sees a vision of himself being relentlessly tortured, he is horrified to experience violent convulsions, spontaneous bleeding, and frightening asphyxiation. And while his sister is always willing to lend a sympathetic ear, she chalks the anomalies up to an unusually potent mix of stress and anxiety. Unfortunately for Ben, his estranged wife, Amy (Paula Patton), isn't nearly as forgiving. A prosaic NYPD medical examiner who has seen her fair share of tragedy, Amy fears that Ben's erratic behavior could be placing their children in danger. Later, as Ben begins to draw connections between his increasingly gruesome visions and a former Mayflower security guard who vanished without a trace, he begins to suspect that an unimaginable evil is using the mirrors as a gateway into the real world, and that his family is in mortal danger from forces beyond their realm of understanding. Perhaps if he Ben can manage to convince Amy that their children's lives are at risk, he can summon the courage to face the greatest evil he has ever known. ~ Jason Buchanan, All Movie Guide
