A tow-truck driver working the grave shift out of Ludlow, California on a lonely Interstate is called out at three in the morning for an overturned big rig. Before he knows it, he's chasing his own truck in a cop car trying to find a murderer in the middle of the Mojave Desert, a murderer who's anything but dumb and desperate. In fact, he has a real purpose in mind: to kill the tow-truck driver and the deputy that's along for the ride.
