The chronically sleepy Donald is responsible for air defense in the army, supported by his three nephews. When he wakes them sleeping with the trumpet, they pull a prank on him and simulate an air strike, causing him to panic and later, as he realizes the prank, to degrade his nephews. Yet, as he later mistakes a buzzing bee for another air strike, he gets them back to the front line and commands them to shoot - right into his eavesdropping tool.
