Is he really who he says he is or could David be hiding a dark side ? Along with his girlfriend Kelly (Amber Heard), his father Jay (Jon Tenney), and Susan's friends (Paige Turco and Sherry Stringfield), they slowly start to piece together the mystery of the man who is set to become his stepfather, but they may be too late in getting to the truth. As the two men get to know each other, Michael becomes more and more suspicious of the man who is always there with a helpful hand. The story begins with Michael Harding (Penn Badgley) returning home from military school to find his mother (Sela Ward) happily in love and living with her new boyfriend, David (Dylan Walsh). 'The Stepfather' is a remake of the 1987 cult classic by the same name staring Terry O'Quinn.
