Title: The Hamiltons Movie plot: A suburban family harbors a dark secret: When their parents are killed in a tragic accident, eldest Hamilton sibling David (Samuel Child) relocates the surviving family members to a quiet California suburb and assumes the responsibility of caring for his orphaned teenage siblings; Wendell (Joseph McKelheer), Darlene (Mackenzie Firgens), and Francis (Cory Knauf). While twins Wendell and Darlene seem to share a bizarre incestuous bond that separates them from the rest of the siblings, Francis acquires a video camera that previously belonged to his deceased parents and sets out preparing a school project about his family. The all-seeing lens of Francis' roving camera begins to reveal that something malevolent is going on inside the Hamilton's picturesque abode. David finds work in a meat-packing warehouse, and is shown to bring some stuff from work home with him, while it is also implied that he is interested in men as he regularly invites male co-workers to go with him to a nearby motel for an evening. One evening, Wendell kidnaps two young girls whom he meets in a local bar and they are tied in their storeroom. Older brother David drains blood off one of them till she slowly dies. Francis gets attracted to the other girl who tries to get him to help her. But things come to a head when Wendell and Darlene murder one of her classmates and feed off her blood. When David tries to kill the other girl, Francis hits him in the head and carries her off to a safe hideout at the meat packing plant which is closed for the night. Wendell asks David to follow Francis, as he is the only one capable of persuading him to return. At the barn, Francis, seeing an open wound on the girl's hand, is unable to control his bloodlust and he kills the girl and feeds off her. When David appears, Francis is crying and we see his fangs. Though terribly sad at his actions, he finally seems to be accepting what he really is: a vampire. With the death of Darlene's classmate, David decides to move somewhere else, and they go to the basement...
