B-movie soundman Jack Terri (John Travolta) has heard it all in his line of work -- until he accidentally records a murder. He follows the sound of a blown-out tire and finds a sinking car and a female survivor (Nancy Allen). But when the vehicle's driver -- a sitting governor and presidential hopeful -- doesn't survive, Jack knows something's afoot. Now, a killer (John Lithgow) wants Jack dead before he can prove the crash was no accident.
