 Early one morning, somewhere in World War II-era Germany, Commander Von Vultur is tempestuously pacing back and forth inside his bunker while fuming and spluttering furiously about how so many American commandos have managed to slip behind German enemy lines undetected and how it would happen if he had sent more troops to guard the country's boundary, while a snippet from Wagner's Das Rheingold plays on the soundtrack.He gets a telegram from the "Gestinko Gestapo", threatening him with his ‘ka-rear’ if he lets ‘vun’ more ‘kommando’ through (the letter is signed "The Apes Of Wrath" and shows three apes' heads; the apes are caricatures of Hitler, Hirohito and Mussolini, the last of whom is crossed out - reflecting the fact of Italy being knocked out of the war by then).The settings recalls World War I trenches more than any actual scene of World War II.
