Father Loomis (Donald Pleasance) is a priest who discovers a strange object in a church basement—a canister filled with a volatile green substance. With the help of Professor Birack (Victor Wong), Loomis discovers the substance is actually the devil's spawn. The evil spirit has been guarded by a group calling themselves "The Brotherhood of Sleep," but the spirit has the ability to free itself whenever it decides the time is right—and it seems that time is just around the corner. Written and directed by horror master John Carpenter, this film is the second installment of his Apocalypse Trilogy.
