Untraceable [Blu-ray]

"Hostel" meets "The Net" in this provocative cyber-thriller about an FBI agent (Diane Lane) on the hunt for a fiendish serial killer who has devised a way of using an untraceable Web site to torture people to death. The more visitors log on to watch the ghastly streaming video, the faster his victims die. Billy Burke, Colin Hanks, Mary Beth Hurt.
