Frank Bigelow is about to die, and he knows it. The accountant has been poisoned and has only 24 hours before the lethal concoction kills him.

Jeffrey Haywood wants to marry to Virginia Embrey. However, Virginia refused to marry unless her older sister, the hard-to-please Angelica gets married first. Angelica, in turn, finds every man she knows too dull and predictable, and for this reason prefers to stay single. Jeff then tries to make Angelica interested in the mild-mannered and timid Reggie Irving passing him off as a notorious playboy to intrigue her. He asks his friend Polly to teach Reggie “how to treat a woman right”, but he turns to be a disastrous learner.
