'Rocket Man and the Aerial Fortress' is an action comedy set in 1918. The story begins with the United States attacked by a rebel faction of the Prussian Army with a giant warring airship. The airship's commander, Baron Von Stryker, is set on restarting WWI by provoking the United States into war with Germany. The US high command calls upon Rocket Man; a brilliant, yet somewhat dim, heroic mercenary, to infiltrate the rogue Prussian high command, destroy the fortress and put an end to the threat.
