Oscar sends Steve to the National Gallery of Art to assist a Countess in stealing The Madonna painting in order to obtain a secret microdot that contains details of the Warsaw Missile Pact. Steve unknowingly is then duped in the theft by the Countess as she switches the painting for a fake one. As Oscar and Steve are tipped off of the fake in the Gallery by the Museum Director, the Countess sells the original for 5 million dollars to an art collector. Then Steve poses as a rich Texas oilman and art collector in order to purchase the original Madonna for 8 million "counterfeit" dollars. As the microdot is now in the OSI, Steve, with the help of the Countess, returns to the Gallery to remove the fake Madonna and replace it with the real one. All is revealed as Steve further assists the Countess on a plane headed to Geneva, Switzerland so she can pay a 5 million dollar ransom to free political prisoners from her country.
