In the 1920s Adriatic Sea, only one pilot rules the skies: Porco Rosso, a talented pilot who, due to a magic spell, has been transformed into a pig. Porco leads a solitary life as a pilot for hire protecting airships from marauding pilots, resting on his private island and visiting his friend, the beautiful hotel-owner Gina. But when a hot-headed American pilot arrives looking to make a name for himself by shooting down The Crimson Pig, Porco enlists the help of a feisty teenage airplane engineer to get his beat up plane into shape for the big fight.
