Blanche Murninghan is enjoying a champagne reunion with her love, Emilio Del Sierra, when Emilio gets news that his long-lost aunt and cousin are under the control of a pair of aged Nazis at an estancia outside Buenos Aires, and they need his help. Posing as tourists, Emilio and Blanche head out to the luxurious pink estancia on the pampa where the Schemmers have taken up management. These escapees from World War II have a lot to hide, including a body, and Blanche is intent on exposing them.
