Breakdown

Jeff Taylor and his wife Amy drive cross-country from Boston to San Diego in their new Jeep Grand Cherokee. Jeff narrowly avoids colliding with a beat-up truck. Later, at a gas station, Earl, the truck driver, confronts Jeff and they exchange hostile words. Shortly after the couple resume their journey, their car breaks down on a vacant road. Leaving Jeff with the Jeep, Amy accepts a ride from a passing big rig trucker to get to a nearby diner and call for help. Jeff eventually discovers that someone has tampered with the Jeep's battery connections. After reconnecting them, he drives to the diner, only to discover that no one has seen Amy. When he sees the trucker on the road and forces him to stop, the trucker claims he has never seen Jeff or Amy. Jeff then hails a passing sheriff named Boyd, but a brief search of the truck yields no sign of Amy. The trucker, Red Barr, is let go and Jeff is instructed by Boyd to see his deputy in the town of Brackett.
