|We first meet up with Carl Fredericksen as a young boy who dreams of being an adventurer as he watches newsreel footage of explorer Charles Muntz. Carl's quiet and sort of shy, but his love of Muntz leads him to Ellie, a sassy little girl who is as outgoing as Carl is introverted. From elementary school through high school and on up into adulthood, Carl and Ellie are inseparable, sharing every moment of joy and sadness together while dreaming of a time when they can actually take off on an adventure in the wilds of South America just like their hero, Muntz. But jobs and health issues and whatnot have a way of intruding on dreams, and Carl and Ellie grow old never having visited the South American jungles. And then, sadly, Carl becomes a widower with just his lovely little house and his beautiful memories of Ellie to keep him company.
|Unfortunately, Carl's home is right in the path of new construction. Unable to stand up legally to those who want to level his house, Carl finds the perfect way to keep his home intact. He wants to visit South America before it's too late and he needs to remove his house from its current location. The solution: ties thousands of helium-filled balloons to his roof and float away.
|But Carl fails to take into consideration the persistent presence of an overly helpful Wilderness Explorer named Russell. Russell didn't know of Carl's planned getaway and was on the porch when Carl's house lifted off. With no way to put the house down and South America set as his goal, Carl and Russell become unlikely traveling companions. Touching down just short of his target landing spot -- Paradise Falls -- Carl and Russell must walk the house (with balloons still attached) a mile or two to the perfect spot.
|On the way to the house's final resting spot they meet up with a huge exotic bird Russell names Kevin and a super friendly dog named Dug. Dug's wearing a fancy collar that allows his thoughts to be translated into English, a plot device that's so incredibly funny that Dug deserves a film all to himself.
|So, now they're in South America and all is as it's supposed to be, right? Nope. There's danger lurking around every corner for poor Kevin, and it's up to Carl, Russell, and Dug to keep the rare bird safe…
