When the story of "Up" begins, the little boy Carl Fredrickson is watching the newsreel attentively. The famous explorer Charles Muntz and His dogs have just returned from a hot-air balloon adventure in South America. Mutz announces the discovery of a new species, but scientists don't believe him and call him a liar. Mutz's reputation is ruined. However, little Karl had no doubt about Mutz's experience and took every word of his words to heart, especially his sentence "Adventure is out there" which was regarded as a wise saying by little Karl. He also wanted to be like Mutz. Become a great explorer. The scene changed. Little Carl was walking home holding a balloon. When he passed by an uninhabited house, the voice of another child came. This was a girl with a tomboy character named Ellie. , she was also obsessed with Mutz's adventure stories. The chattering Ellie used the weathervane on the roof of the house as a joystick and the whole house as a big spaceship. She tried her best to persuade the overwhelmed Carl to join her plan and sit "flying" House" adventure. Of course, the two children did not fly up, but fell down. But Carl and Ellie got to know each other. Later, the camera showed us a montage of them growing up, getting married, and living together. Ellie became a zookeeper, and Carl built a car to sell helium-filled gases. balloons. Both of them had dreamed of exploring the "Paradise Falls" in South America mentioned by Mutz all their lives, but they were always tired of running for life, and they could not realize it until Ellie died of illness. After Ellie's death, Carl (voiced by Ed Asner) became withdrawn and unwilling to interact with others. But what's worse is that his house happens to be on land planned by the government for development, where a skyscraper is about to be built. Carl, who was unwilling to move out, became a "nail house", and the government sent people to prepare him to be sent to a nursing home (John Ratzenberger, who has voiced in every Pixar cartoon, this time played the role of a construction worker who quarreled with Carl. Dubbing), but just before those people came, Carl made the decision to leave here with the house and head to South America to realize the dream of his wife and him! So we saw the classic scene in the trailer, where colorful balloons dragged an entire house and its foundation into the sky. The picture of the flying house overlooking the earth in the air is very beautiful, which was the "initial inspiration" that led the creator to create the entire film. But what Carl Lao didn't expect was that his "flying house" would take a "stobber" - a 9-year-old Asian boy named Russell (voiced by Jordan Nagai). This overly optimistic little boy likes to go fast. He kept talking, he joined the Wilderness Explorers Association, and in order to become a senior member, he needed to collect a badge, which he could get by helping the elderly. Unfortunately, the target he chooses to help is the eccentric Carl, who hates this little chubby guy following him around all the time. Carl thought of many ways to throw the annoying kid from the "flying house" (this part is very funny), but before he could implement it, a storm forced him to work with Russell *** , allowing the "Flying House" to successfully fly out of the heavy rain clouds. Afterwards, the flying house landed at its destination, Table Mountain, in South America. From here, the two people began to pull the "flying house" forward on foot. When the story begins, the little boy Carl Fredrickson is watching the newsreel attentively. The famous explorer Charles Muntz and his dogs have just returned from their South American adventure in a hot air balloon. Muntz Munz announced the discovery of a new species, but the scientists did not believe him and called him a liar. Munz's reputation was ruined. However, Carl Jr. has no doubt about Munz's experience and takes every word of his words to heart, especially his sentence "Adventure is out there" which is regarded as a wise saying by Carl Junior. He also wants to be like Munz. Become a great explorer.

After saying goodbye to Big Bird, the two of them drove Monz's airship back to the city. Ronaldinho also received the badge awarded by Karl. The three "people" became inseparable good friends and lived a happy life. A comfortable life (just like Ronaldinho described when talking to Carl about his family situation). And their flying house finally floated alone with the balloon on the edge of the Wonderland Falls in the "Mesa Mountains" (while Monz's whereabouts were unknown), realizing Ellie and Carl's lifelong dream.
