At a gas station he picks up Antoinette, a stuck-up blonde from a rich family, who was left behind without a penny by her husband on their wedding night. Billy likes her looks and hires her as his assistant. She seems to bring them bad luck and the business gets even worse. In these hard times she loses her reluctance and starts to like her new way of life... and Bronco Billy. Written by Tom Zoerner
