Untraceable stars Diane Lane, Colin Hanks, and Billy Burke. Jennifer Marsh (Lane) is an FBI agent on a mission to find a virtually untraceable serial killer. The murderer posts live videos of his victims on the web. The more people who watch the videos, the more painful and vicious the murder is. Marsh is running out of time as murderer hits close to home. Untraceable is a thrilling, suspenseful movie that taps into the psychology of the media and public’s obsession with evil. Untraceable will be in theaters on January 25.
