Carl Fredricksen idolizes explorer Charles Muntz. When accused of fabricating the skeleton of a giant bird he brought back from Paradise Falls in South America, Muntz leaves, and vows not to return until he has captured one alive. Carl meets a girl named Ellie, also a Muntz fan, who confides her desire to move her "clubhouse"—an abandoned house in the neighborhood—to a cliff overlooking Paradise Falls. The two later marry and live in the restored house, and Carl works as a balloon salesman. Suffering a miscarriage and unable to have children, they decide to save up to go to Paradise Falls, but are constantly forced to spend their savings on more urgent needs. Now elderly, Carl finally arranges for the trip, but Ellie falls ill and dies.
