A quartet of international crooks -- Peterson, O'Hara, Ross and Ravello -- is stranded in Italy while their steamer is being repaired. With them are the Dannreuthers. The six are headed for Africa, presumably to sell vacuum cleaners but actually to buy land supposedly loaded with uranium. They are joined by others who apparently have similar designs.

Billy Dannreuther:
The only thing standing between you and a watery grave is your wits, and that's not my idea of adequate protection.
Revealing mistakes: When we see the newspaper article about Vanmeer's murder, early in the film, only the first paragraph belongs to the story; what we can see of the second and third paragraphs is about a need for new school buildings.
With more than a million titles, it isn't feasible to handpick recommendations for every film. That's why we came up with a formula to suggest titles that fit along with the selected one. The formula uses factors such as user votes, genre and keywords to generate an automatic response. The system produces relevant results most of the time but since recommended titles are not manually chosen, occasionally they may include less than perfect matches.
