A courageous WWI Pilot is transformed into a pig by a mysterious curse. He is now employed as a paid mercenary/problem solver and sea plane pilot in the Adriatic Sea for the side of good, forced to do combat with a band of unwashed air pirates. Anarchy and war are coming to Italy and the adriatic pilots are being forced to join the Air Force or become fugatives from the law. Our hero Porco is shot down in a dogfight with a self styled air ace called Curtis. After Piccolo fixes his plane, he must fight Mama Aiuto, run from the Italian government, engage in a final showdown with Curtis whilst courting the lovely Gina and save young school girls from the clutches of Mama Aiuto. In addition to this, he must pay back Papa Piccolo for the renovation of his airplane, win a bet, break the curse, and save himself in the bargain. Is this too much for our hero Porco? Can he face up to the challenge and come out with style and grace?
