A long time ago the two men made an agreement that they would sign over one third of their company to their oldest children when they turned twenty-one, with the condition they married each other within thirty days.
Vicki hires an exotic dancer, Mikki Marquette, to play the role of her and lure John into a trap.
Since the wedding is to take place in Havana according to the contract, Vicki, Mikki and John all board a train to Miami, where a ship will take them to Cuba.
In Miami, John meets a playboy fortune seeker who calls himself Lord Percy Ticklederry, and sends him in Mikki's way.
In Havana, Percy decides to confess his real identity to Mikki, and tells her he is no English lord, just an ordinary guy from Brooklyn.
