Ten-year-old Carl Fredricksen idolizes famed explorer Charles Muntz, who is discredited when a giant bird skeleton he brought back from Paradise Falls in South America is deemed a fake. Muntz travels back to the falls, vowing not to return until he brings back a live specimen.
Carl befriends Ellie, another young Muntz fan, who keeps a scrapbook of her adventures and dreams of moving her “clubhouse” (an abandoned house) to Paradise Falls and have adventures of her own. Carl and Ellie eventually marry, renovate the clubhouse and move in. They work at the city zoo as a balloon salesman and zookeeper, respectively. Ellie suffers a miscarriage, and it is implied that she cannot have children. Though the couple saves money for a trip to Paradise Falls, they must repeatedly spend their savings on more pressing needs. Many years later, a now elderly Carl decides to surprise Ellie with tickets to South America, but she falls ill and is hospitalized. Ellie gives Carl her scrapbook before she dies.
Now in his late 70s, Carl decides to keep his promise to Ellie to move their house to Paradise Falls by attaching thousands of balloons to it. Russell, a young “Wilderness Explorer” scout attempting to earn his final merit badge, becomes an accidental stowaway. After a storm propels the house to South America, the real adventure begins.
Along the way, Carl and Russell encounter a giant bird named Kevin and a talking Golden Retriever named Dug. Their journey takes a dangerous turn when they meet Charles Muntz, whose obsession with capturing the bird leads to a thrilling chase. Loyalties are tested, and sacrifices must be made to protect their newfound friends.
Despite facing numerous challenges, Carl finds renewed purpose and strength as he fights to protect his home and save his friends from danger.
