An attractive woman is driving down a lonesome road at night and she suddenly has to brake for a girl who dangerously runs in front of her car. Roberta doesn't hit the girl, but she lies on the ground unmoving and bleeding. She notices that the girl was shot and that the killer watches her from the bushes. She flees and informs the police, yet when they arrive there's no evidence of a crime at all.
