A killer with a penchant for inventive and macabre deaths challenges an FBI Agent with an equally unusual imagination and sense of humour.

SA Ellie Conway works serial crime cases. When someone tries to kill her, it becomes obvious it's linked to her after-hours pursuits in cyberspace. Matters become complicated when her assailant is found dead in the trunk of her car.

Despite a plethora of crime scenes, no evidence can be found to identify a motive or perpetrator. The death toll rises and eventually includes those close to her. A chance remark provides the first real clue to unraveling the killer's twisted goals.
