The plot is a parody of the Three Little Pigs, told from a Second World War anti-German propaganda perspective. In this cartoon, the pigs go to war against Adolf Wolf (Adolf Hitler), who is set on invading their country, Pigmania. The two pigs who built their houses of straw and sticks claim they don't have to take precautions against the wolf, because they signed non-aggression pacts with him. The pig who built his house of stone, "Sergeant Pork" (an homage to Sergeant York), does take his precautions and outfits his house with defense machinery.
