The Hamiltons (2006)

The Hamiltons seem to be a normal family in a small town in California. The suddenly deaths of the parents forces David, the oldest one, to take care of the three remainder, including youngest Francis and the corrupt twins Wendell and Darlene. Sensitive Francis often uses a camera to work on a project about family and inadvertently discover a tortured girl in the cellar and then unwillingly discloses the tragic of his evil family.
