Con man Eli Kotch (James Coburn) charms his way into a parole by playing on the emotions of a pretty psychologist (Marian McCargo), but drops her at the first opportunity to move around the country, romancing women and then stealing their possessions, or those of their employers. He's made a down payment on the blueprints to a bank at Los Angeles International Airport, but needs to raise $85,000 to complete the purchase.
