In the Sanctuary, a cult religion's inner-city haven from the outside world, members of the group are meeting bizarre deaths. One by one they are killed in a gruesome method that suggests a Biblical revenge.

Detective John Maiden returns to solve the case, but in the Sanctuary everyone loves everybody else. They share the same rooms, the same church, the same swimming pool and gymnasium – even the same bed, when no one's looking – and everybody has something to hide. In the close-knit, secretive environment of the Sanctuary, modern police methods and forensics are useless. Every crime scene is saturated with evidence from all the clan members. Each murder is as good as a clean kill and Maiden has to rely to all of his wits and experience to find the killer.
