Faced with the most baffling and menacing case of her life, FBI agent and cybercop Jennifer Marsh (Diane Lane) must race against the clock to stop a deadly Internet predator in his tracks -- before more innocent lives are extinguished. So begins director Gregory Hoblit's (Primal Fear) heart-stopping thriller Untraceable. The psychopath at hand is far from an ordinary villain; a megalomaniacal showman with a flair for sadistic braggadocio and astonishing technical knowhow, his expertise makes it infinitely more difficult for Marsh to track him down.
