Banker Christopher Price from the humdrum town of Keetoosen, Ohio, is happily married to Mary, and the couple are just about to go to New York on their second honeymoon.

However, Chris' old childhood friend Joe Parker, a known newspaper reporter who has been stationed abroad, sends him a message just before they begin their journey.

Joe arrives in Keetoosen before the couple leaves, and explains that he has lied to his boss about being married to Mary, to get a longer vacation in the past.
