Ted Wiggins is an idealistic 12-year-old boy [citation needed], who lives in "Thneedville", a walled city that, aside from the human citizens, is completely artificial; everything is made of plastic, metal, or synthetics. Ted has a crush on local environmentalist Audrey, who wants to see a "real tree" more than anything in the world, and decides to find one in order to impress her. His energetic Grammy Norma secretly tells Ted the legend of the Once-ler, who will tell anyone about trees if you brought him fifteen cents, a nail, and a shell of a great-great-great grandfather snail. When Ted leaves Thneedville in search of the Once-ler, he discovers that the outside world is a contaminated, empty wasteland. Once the boy finds him, the Once-ler agrees to tell Ted about the trees on the condition that he listens to the story over multiple visits. Ted agrees, but on his way home, he encounters the mayor of Thneedville, Aloysius O'Hare, who is also the proprietor of a company that sells bottled oxygen to Thneedville residents. O'Hare explains to Ted that because trees produce oxygen free of charge, he considers it a threat to his business whenever he hears people talking about them. After revealing that he has "security camera eyes" all over the city, O'Hare pressures Ted to stay in town. However, Ted continues to sneak out of O'Hare's sight (with his grandmother's encouragement) and learns more of the trees' history.
