Pepper is a rambunctious big man, and, suddenly, the surprised inmate of a budget-strapped mental institution in Queens, New York. He’s not mentally ill, but that doesn’t seem to matter. On his first night, he’s visited by a terrifying creature who nearly kills him before being hustled away by the hospital staff. It’s no delusion: The other patients confirm that a hungry devil roams the hallways when the sun goes down. Pepper rallies three other inmates in a plot to fight back: Dorry, an octogenarian schizophrenic; Coffee, an African immigrant with severe OCD; and Loochie, a bipolar teenage girl. Battling the pill-pushing staff, one another, and their own minds, they try to kill the monster that’s stalking them. But can the Devil die?
