Sissy Hankshaw (Uma Thurman) is born with enormous thumbs that help her hitchhiking through the U.S. from a young age. She becomes a model in advertising, and her New York agent, "the Countess" (Sir John Hurt), sends her to his ranch in California to shoot a commercial, set against the background of mating whooping cranes. There, she befriends Bonanza Jellybean (Rain Phoenix), one of the cowgirls at the beauty ranch. The cowgirls take command of the ranch from the Countess and drug the cranes with peyote. The Police besiege the ranch.
