The story follows the adventures of Horton, an elephant, who one day hears voices coming from a speck of dust. He soon discovers that within this tiny dust speck exists the smallest planet in the universe. Although Horton is ridiculed by the other animals from the Jungle for believing in something that he cannot see, he stubbornly persists in his quest to save the Whos.

Living on this planet are a tiny race of creatures known as "Whos", including the Mayor, his wife and their son Jojo. The Whos are having their own adventures, including a war over which side their bread gets buttered! Jojo is sent away to boarding school for the crime of thinking - an activity not encouraged by his parents and teachers!

Events in the Jungle of Nool and on Who run in parallel as Horton and Jojo continue to do what they think is right, becoming firm friends along the way.

Among the adventures are Horton being sold to a circus, facing a trial back in the jungle and Jojo joining the Whos Military Academy. However, a happy ending is guaranteed when everyone eventually agrees with Horton that "a person's a person, no matter how small".
