"There's no place for dreams on the streets of Vegas"

Speedway Junky

A naive drifter runs away from his army father in hopes of making it on the car racing circuit. In Las Vegas, he meets a young scam artist, who develops a crush on him. He is then introduced to a whole gang led by a young hustler. The racer-to-be then gets a lesson in the wild side, getting involved in one situation after another.
