At the end of an alternate World War II, a new European country is formed called Gorongo. General Giovanni of the Gorongo military was infuriated with the results of the war and what it meant to the country of Gorongo, initiating a rebellion against the country’s government that was widely followed by his soldiers. Holing themselves up on Bobo Island, south of Gorongo, Giovanni declared the occupation as the independent state of Fuangania and plotted to take over Gorongo. After taking over the town of Kusunoki, the Fuangania invasion – consisting of massive ground and sea attack forces – started to spread. Gorongo President Bratt ordered a counterattack that focused on the one type of firepower Giovanni lacked: an air force. The special air force "Daisenpuu" sets up a mountain base after spotting a secret Fuangania fortress under construction. However, nearing the end of their training, the airforce is spotted by the Fuangania and are preparing to attack. It's up to the player, in the role of the Wing Commander, to fly into Giovanni's secret base and take him and his commanding unit out.
