It's 1932. Prohibition rages, the Depression ravages, and Billy McGlory comes of age whether he wants to or not. Musical and adventurous, Billy dreams of having his own ritzy supper club and big band. On the eve of his marriage to the pregnant Prudence, the shifty "businessman" Rosario Ingovito offers him all that and more. Fame, fortune, his own Broadway musical-it's all his for the taking, despite Pru's opposition to Rosie's ventures. Meanwhile, Pru's artistic career gains momentum and their child is born. Can anything go wrong for Billy? Only when he gets in way over his head does he stop to wonder how his business partner really makes his millions, but by then it's far too late...
