College student Casey Beldon (Odette Yustman, CLOVERFIELD) begins having dreams about a spooky little boy with bright blue eyes. She thinks nothing of it as first, but when the image becomes a recurring motif and the boy she babysits for hits her in the face and tells her 'Jumby wants to be born now', she begins to get frightened. After learning that she had a twin brother who died in utero, she finds a photo of her late mother with the same ghostly child looming in the background. A newspaper clipping then leads Casey to visit an elderly Holocaust survivor (Jane Alexander) in a nursing home. The woman clues her in to a dark family secret extending back to WWII, which prompts her to employ the services of Rabbi Sendak (Gary Oldman), whose scepticism about evil spirits is vanquished when he sees what he is up against.
