Summer vacation is here. College girl Grace Andrews (Sophia Bush) and her school boyfriend Jim Halsey (Zachary Knighton Kyle Davis) plan to drive to Mexico to experience a romantic and exciting road trip. On the way, they bump into John Rider (Sean Bean), a passerby with an unusual look, who asks for a ride. Although the two college students hesitated, they agreed to John's request. But a nightmare began. John made no secret of his murderous plan in the car. He enjoyed killing people, and his target might be the two unarmed college students in front of him. Grace and Jim were terrified. After a thrilling fight, they finally pushed John out of the car and fled in a hurry. Is the nightmare over? Or is everything just beginning?
