Three years after his release from Camp Green Lake, Theodore “Armpit” is living in Austin, Texas trying to build a stable lifestyle by working for a landscaping company and caring for his neighbor Ginny McDonald, a ten year old girl with cerebral palsy. He meets Rex "X-Ray" Washburn, a friend from Camp Green Lake, who asks for his help in a ticket scalping scheme for teen pop star Kaira DeLeon's upcoming concert. Armpit tries to use two tickets to impress a crush, who cannot go; instead, he takes Ginny, but when they present the tickets, they are forged, and Armpit is beaten and handcuffed by police officers. Ginny has a seizure, which the officers misinterpret as a reaction to drugs. When singer Kaira finds out, she invites them backstage, and she later forms a friendship with Armpit.
