Directed by Gregory Hoblit (Fracture, Primal Fear), Untraceable follows F.B.I. cybercrimes specialist Jennifer Marsh (Diane Lane) as she attempts to track down a serial killer who brazenly displays his murderous deeds on the internet. Aided by fellow agent Griffin Dowd (Colin Hanks) and local detective Eric Box (Billy Burke), Marsh tenaciously hunts for the elusive criminal but as she closes in on her target, he deviously finds ways to get closer to her, all the while killing his victims in increasingly faster fashion.
Untraceable clearly references a number of renowned thrillers, most notably the SAW films, Seven, and Silence of the Lambs. Lane's steely, smart, and beautiful heroine ably anchors the film, which also benefits from its appropriately gloomy Portland, Oregon, backdrop. As with any effective suspense movie, the thrill is in the chase, with the cold-blooded killer proving to be quite adept at disguising his real location, even as his disturbingly popular site remains prominently on the web.
