The summer vacation is coming. Female college student Grace Andrews (Sophia Bush Sophia Bush) and her school boyfriend Jim Halsey (Zakary Nieton Kyle Davis) plan to drive all the way to Mexico for a romantic and exciting road trip. On the way, he came across an unusual-looking passer-by, John Ledell (Sean Bean), and asked for a ride. Although the two college students hesitated, they agreed to John's request. How do you know the nightmare has been happening ever since. John made no secret of his plan to kill people in the car. He took pleasure in killing people, and probably targeted two unarmed college students in front of him. Grace and Jim were so frightened that a thrilling struggle finally pushed John out of the car and ran away. Is this the end of the nightmare? Or is it just the beginning?
