The episode begins with Lisa Simpson feeling a deep connection to nature as she observes a tree in her neighborhood. She is particularly moved by the beauty of the tree and expresses her desire to protect it. Meanwhile, Homer and Marge are preoccupied with their own lives, and Bart is more interested in causing mischief. Lisa's passion for the tree leads her to join a local environmental group, where she meets a charismatic activist named J. R. He inspires her with his dedication to saving trees and the environment.

As Lisa becomes more involved with the group, she learns about a plan to cut down the tree she loves to make way for a new parking lot.

Despite their doubts, Lisa's resolve strengthens, and she organizes a protest to raise awareness about the tree's plight.
