Columbus, Ohio, Homicide Detectives, Michael McConnell and Aaron Simmons, investigate the brutal murders of two women. There are no witnesses and few clues, except for unfamiliar words the killer has printed in lipstick on each victim-words which have demonic connotations, making the detectives wonder if they are dealing with a serial killer or a demon from Hell. As McConnell and Simmons dig for the truth, they discover a decades-old third murder with the same MO. This victim had ties to a mysterious club, The Paradise Coven, that may be responsible for all three murders. Unfortunately, the terrible secret the detectives unravel may have far-reaching consequences.
