The peaceful, music-loving undersea kingdom of Pepperland, a sudden invasion by the Blue Meanies throws the land into gloom.

lThe Mayor travels to the surface world in the Yellow Submarine to recruit help, where he finds The Beatles which agree to journey back to Pepperland. 

Eventually, they disguise themselves as the Sgt. Pepper’s band, and use the power of music to restore color, joy, and freedom to the kingdom.
