Detective Maud Graham lives a secluded life, though, on occasion will have a 16-year-old male prostitute, named Gregoire, stay over. Graham's most recent case is tracking a serial killer who mutilates his victims, all athletic women in their 30s. Graham believes the killer collects human parts to reconstitute the body of his late mother, and hopes to lure the killer in by using one of Gregoire's regular customers as bait.
