Years after being traumatized by a hitchhiker, Jim Halsey (C. Thomas Howell) is trying to piece his life back together. After being suspended from the police force, he decides to return to Texas to speak with a friend about his problems. He reluctantly agrees to let his girlfriend, Maggie (Kari Wuhrer), join him. As they drive, Maggie lets a stranded driver (Jake Busey) into the car. Halsey becomes suspicious and kicks him out, but the stranger returns, undeterred, to wreak havoc.
