Casey Bell (Yustman) hated her mother for leaving her as a child. But when inexplicable things start to happen, Casey begins to understand why she left. Plagued by merciless dreams and a tortured ghost that haunts her waking hours, she must turn to the only spiritual advisor, Sendak (Oldman), who can make it stop.

With Sendak’s help, Casey uncovers the source of a family curse dating back to Nazi Germany-a creature with the ability to inhabit anyone or anything that is getting stronger with each possession. With the curse unleashed, her only chance at survival is to shut a doorway from beyond our world that has been pried open by someone who was never born.
