Three robbers, Lylle Corbett (Mitchell), Dolph Kostis (Salter), and Darlene (Mansfield), steal one-million dollars from a shipment on its way to the United States. But, instead of sharing the dough with Lylle, Dolph, decides to kill him, without Darlene (who likes them both), knowing it. When returning to Darlene (his wife), at the Hotel Americano's, Dolph, informs her that Lylle is out of the picture and that she should forget about him. Before Dolph had returned, Darlene, had been visited by the hotel's manager Livio Morelli (Braun), who was there to request her to turn down the volume on her radio. Livio sees a one-thousand dollar bill under the edge of the bed, and quickly knows that they are the robbers; that he had recently heard about on the radio; and that they call themselves "Mr. and Mrs. Smithopolis".
