A heroic guerilla group fights back against impossible odds during the 1941 Nazi invasion of Russia.

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).
