They meet up with the man at a truck stop down the road and when he asks Jim for a ride into town, Jim feels obliged to help. Unfortunately Grace's feelings were correct as the man turns out to be a psycho who torments them until they are able to throw him out of the car.
Even though they are unnerved, they end up pulling off the road to sleep and the next day are passed by a family in a station wagon, who are giving the same psycho a ride. They crash their car trying to warn the family, and stumble upon the poor family later, who have become victims. Driving the family's car to a truck stop to ask for help, they are arrested for the murders.
The original Hitcher movie scared me, but this one didn't have the same effect. I didn't feel the tension the first movie had. Plus the characters did some really stupid things. If a psycho killer and the police are after you, would you really feel comfortable enough to get naked and take a long shower? This killing machine keeps showing up everywhere they go, yet they aren't concerned about being naked and vulnerable.
