The 1989 thriller that shot Lost star Terry O'Quinn to cult stardom serves as inspiration for this remake penned by J.S. Cardone and directed by Nelson McCormick. When a teenage boy (Penn Badgley) begins to suspect that his new stepfather (Dylan Walsh) is a notorious serial killer who preys on broken families, he races to gather the evidence that will back up his claim before it's too late. Sela Ward co-stars in the Screen Gems release. ~ Jason Buchanan, All Movie Guide
