Synopsis

Charlie Rogers, a singer at an espresso cafe, gets into a fight with three unruly characters and after expertly dispatching them with karate, leaves the nightspot and heads for points unknown on his motorcycle. After wandering a bit, Charlie gets a job as a "roustabout" or handyman in a carnival run by Maggie Morgan. At the carnival Charlie meets Cathy Lean and falls for her.
Business at the carnival is practically nil, so, in between jobs, Charlie breaks into an impromptu song on the midway. News of this gets around and suddenly droves of young people flock to the carnival. A new career is launched for Charlie.
Things soon sour when Charlie gets into a fight with one of the customers and decides to leave the carnival. He feels all washed up and sure that he has lost Cathy , so he heads for a rival carnival which had previously made him an offer.
With Charlie gone, Maggie's carnival takes a nose dive and the creditors come knocking at its doors. With only one chance left, Cathy goes to Charlie and persuades him to return and save the carnival.
