The Passing (2011)

The three Naibert children, in their teens and early twenties, inherit a vast estate from their grandmother Rebecca. But unknown to them, the family inheritance has passed from grandmother to granddaughter for centuries—and Rebecca has a long reach from the grave to assure that the line is unbroken. The first weekend in the mansion is a party for the three Naiberts and their friends—but one by one, they vanish without a trace. Is death the punishment for violating Rebecca's spell? Are the demons that beset the young people real—or only reflections of their own fear? Is it murder, violence from another dimension, or madness? The answer lives in the reflections.
