Rio is a movie that is animated and full of bright colors and festive music. The movie is called Rio because the majority of the movie takes place in Rio de Janeiro which is in Brazil. But the story starts in cold and snowy Minnesota where Blu, a macaw bird of the male species, lives with his owner who is named Linda. They have a very peaceful and safe life. She owns a bookstore and he is a very pampered bird who does not know how to fly.
Tulio Monteiro is a scientist who studies birds and is looking for a mate for his female macaw bird that lives in Rio. Tulio explains the direness of the situation to Linda. The blue macaws are going to become extinct unless Blu comes to Rio to mate with the female macaw that is named Jewel. Linda feels propelled to do the right thing and decides that she and Blu will go with Tulio to meet Jewel and allow the birds to mate.
Blu is instantly attracted to Jewel and knows he has found love. Jewel is angry that she is in a cage and wants to be released to the wilderness. The birds are stolen but thankfully are able to get away where they fly into the forests.
Blu and Jewel meet all kinds of other friends on their adventures including a bulldog and a touscan. Meanwhile Linda and Tulio have discovered their birds have been taken and set out on a quest to find them and bring them back to safety. Blu and Jewel have been chained together which is a problem since Blu cannot fly and Jewel wants to fly everywhere.
When the chain is finally broken, Jewel is captured and taken to Rio where Carnival is happening. Meanwhile, Linda and Tulio are doing their own detective work trying to track them down. They end up deciding to dress up as the birds they care so much for and participate in Carnival in hopes of tracking them down. When they all end up in Rio during a magical night of Carnival anything can happen, including love.
