Now teenagers navigating a grittier Elwood City, they confront bullying, family struggles, identity crises, and the loss of innocence that comes with growing up. Arthur's optimism is tested as he discovers the world isn't as fair as he once believed. His relationships fracture under pressure—Buster grapples with his parents' divorce, Francine battles perfectionism and anxiety, and Binky's tough exterior hides deep insecurity.
