Adams is leaving for a trip to California. His mother doesn't want him to go because she thinks it is dangerous for him to drive that far and tells him not to pick up any strangers.
When Adams was crossing the bridge he saw a man that was leaning on the cables of the bridge. The man jumped out in front of him and he had to swerve out of the way.
Adams would have forgot about the man on the bridge if he didn't see him again on the side of the road. This time when he saw him though the man was holding out his thumb trying to get a ride. Then just a little bit later he saw the hitchhiker again trying to stop him.
Adams thinks he should have somebody in the car with him so he stops on the side of the road to see if a girl he sees needs a ride. The girl gets in the car and tells him thank you she has been walking for a while. Then he tells her about the guy he keeps seeing and the girl gets a little freaked out and gets out of the car.
Adams calls home to speak to his mother but his mother isn't there. He finds out his mother is in the hospital from a nervous breakdown. Adams dose't under stand though because his mother is never nervous but then he finds out it is because her oldest son died 6 days ago in a car crash and he is her oldest son.
Once adams finds out that his mother is in the hospital and he is dead. He now knows why he has been seeing the Hitchhiker since the bridge as a representation as his death.
