 Blue-collar worker Vince stumbles into a dance school, where he quickly becomes entranced by the music. Miss McKenzie, the school s manager and former owner, is about to throw him out on his ear when Moon, the school s rebellious new jazz instructor, vouches for him. Although the school s new owner has insisted on bringing in Moon as a teacher, Miss McKenzie absolutely hates him and the influence of his mordern music, and will stop at nothing to see him (and Vince) thrown out for good.
