Carl Fredricksen spent his entire life dreaming of exploring the globe and experiencing life to its fullest. But at age 78, life seems to have passed him by, until a twist of fate (and a persistent 8-year old Wilderness Explorer named Russell) gives him a new lease on life.
A couple of angels, O’Reilly and Jackson, are sent to Earth to make sure that their next supervised love-connection succeeds. They follow Celine, a spoiled rich girl who has just accidentally shot a suitor and, due to a misunderstanding, is kidnapped by janitor Robert. Although Celine quickly frees herself, she stays with Robert for thrills. O’Reilly and Jackson pursue, hoping to unite the prospective lovers.
