The Two Yanks in Trinidad are gangsters Tim Reardon (Pat O'Brien) and Vince Barrows (Brian Donlevy), who split up over a disagreement and join the army, Tim to escape Vince's wrath and Vince to get his lunch-hooks on Tim. Both of our heroes run afoul of Army discipline and protocol in general, and tough top sergeant Valentine (Donald MacBride).
