Mom’s (Sela Ward) new boyfriend, David (Dylan Walsh), isn’t quite right and Michael knows it. A series of mysterious events leads the teen to suspect that David might in fact be a dangerous serial killer known for preying on families. Now, all he needs to do is gather evidence before it’s too late. Nelson McCormick directs this spine-tingling remake of the 1987 thriller based on the real-life story of killer John Emil List.
