Gar Evans (William Powell) agrees to promote Ginsburg's product, artificial Natural rubber created from sewage, only after his friend Mike Donahey (Frank McHugh) assures him it is not a scam. Gar is superstitious; he believes he will only succeed if his long-suffering girlfriend Francine Dale (Evelyn Brent) joins them on the venture. She, however, has given up on him, especially since he left her five days before to pick up something, and never came back. It is only with great effort that he convinces her to give him another chance.
