In Rio de Janeiro, baby macaw, Blu, is captured by dealers and smuggled to the USA. While driving through Moose Lake, Minnesota, the truck that is transporting Blu accidentally drops Blu's box on the road. A girl, Linda, finds the bird and raises him with love. Fifteen years later, Blu is a domesticated and intelligent bird that does not fly and lives a comfortable life with bookshop owner Linda. Out of the blue, clumsy Brazilian ornithologist, Tulio, visits Linda and explains that Blu is the last male of his species, and he has a female called Jewel in Rio de Janeiro. He invites Linda to bring Blu to Rio so that he and Jewel can save their species. Linda travels with Blu and Tulio to Rio de Janeiro and they leave Blu and Jewel in a large cage in the institute where Tulio works. While they are having dinner, smugglers break into the institute and steal Blu and Jewel to sell them. Linda and Tulio look everywhere for Blu, who is chained to Jewel and hidden in a slum. Meanwhile, Jewel and Blu escape from their captors and befriend a group of birds that help them to get rid of the chains. It is Carnival and the smugglers and mean cockatoo, Nigel, do not intend to give up Blu and Jewel, and chase the birds through the crowded streets. jesse，姐已经看着你破了6次处了，咱们能干点别的嘛。。。？。闹场记。爱之吻的激励哟，海归男子关键时刻勇救受伤女友！。惊险刺激，美轮美奂。梦想的力量。宅男有梦，驭爱飞翔。回归本性的飞翔冒险。让我紧紧地抱着你在空中飞翔。关于飞翔的华丽冒险。里约大冒险。 阿蓝（Jesse Eisenberg 配音）是一只世界上极其稀少的蓝色金刚鹦鹉，当他还是雏鸟时，便被可鄙的偷猎者从里约的热带丛林中掳到美国。阴差阳错，他变成了小女孩琳达的宠物，从此相伴多年，如今的阿蓝俨然一个养尊处优的宅男，甚至到忘记了如何飞行。某天，名叫图里奥（Rodrigo Santoro 配音）的鸟类学家经过琳达（Leslie Mann 配音）经营的书店，他被阿蓝所震惊，并希望能将阿蓝带回里约，与世上仅存的另外一只雌鸟繁衍后代。 虽然心怀不安，但是考虑到蓝色金刚鹦鹉的命运，琳达还是带着阿蓝来到里约。阿蓝顺利见到了美丽的同类茱儿（Anne Hathaway 配音）。茱儿则一心逃离樊笼，回归大自然。与此同时，一伙犯罪分子盯上了这群可爱的小生灵……
