Untraceable is a 2008 American crime thriller film directed by Gregory Hoblit and starring Diane Lane, Colin Hanks, Billy Burke, and Joseph Cross. It was distributed by Screen Gems.
Set in Portland, Oregon, the film involves a serial killer who rigs contraptions that kill his victims based on the number of hits received by a website KillWithMe.com that features a live streaming video of the victim. Millions of people log on, hastening the victims' deaths.
Special Agent Jennifer Marsh (Diane Lane) is a widowed single parent living in a suburban Portland home with her daughter, Annie Haskins (Perla Haney-Jardine), and her mother, Stella Marsh (Mary Beth Hurt). At night, she works in the FBI's cybercrime division with Griffin Dowd (Colin Hanks), fighting identity theft and similar crimes. One night, an anonymous tip leads them to a website called KillWithMe.com. The site features a streaming video of a cat being tortured and killed. The website cannot be shut down, as the creator knew that someone would try and built into it a fail-safe; every time the server is closed, a mirror server immediately replaces it.
