Cynthia's best friend, Annie, falls head over heels for the new high-school librarian, but after meeting Mr. Gabriel, Cyn realizes something isn't quite right. Maybe it's the creepy look in the librarian's eyes...or the blood and horns and bat-like wings that appear when he thinks no one is looking. He's a demon...and now Cyn has to save her best friend from the clutches of the evil librarian, who also seems to be slowly sucking the life force out of the entire student body!
