Show synopsis A serial killer with a sickening knack for showmanship and a keen sense of technological know-how sets up a graphic website to taunt the FBI and display his gruesome handiwork in this dark thriller directed by Gregory Hoblit (Primal Fear and Frequency) and starring Diane Lane. As a cybercimes investigator on the frontline of the war against virtual criminals, Special Agent Jennifer Marsh (Lane) thought she had seen it all. She realizes just how wrong she is, however, when she learns of a technologically advanced psychopath who has set up the world's first-ever snuff website. Audience participation is key on the ingenious killer's website, because the more hits his page gets the quicker he is to dispatch his victims. But how does one catch a killer who has covered their cyber-tracks with the web-savvy skills of a world-class hacker? Now, as the hunt becomes personal, Marsh vows to use every resource at her disposal in order to catch the killer before he logs on for another round of cyber slaughter. ~ Jason Buchanan, Rovi Hide synopsis
