As a grandfather tells a story to his disinterested but captive grandson, we are transported to the adventures of the beautiful Buttercup who is kidnapped by the dastardly Prince Humperdinck, and of Westley, her childhood beau, who has returned in the guise of hero Dread Pirate Roberts, and teams up with the great swordsman Inigo Montoya to go to Buttercup’s rescue.
