Gary Oldman

Sometimes the soul of a dead person has been so tainted with evil that it is denied entrance to heaven. It must endlessly wander the borderlands between worlds, desperately searching for a new body to inhabit.

And sometimes it actually succeeds.

Casey Beldon (Odette 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 (Gary Oldman), who can make it stop.
