Dr. Park (Sandra Oh), a psychiatrist, is interviewing Arthur Poppington (Woody Harrelson), a vigilante known as "Defendor", who tells about assaulting a police officer who claims to be working undercover. Dooney (Elias Koteas) is a corrupt detective who Defendor believes is in the employ of his nemesis, "Captain Industry," who Arthur blames for his mother leaving him as a child, dying of drug abuse later; his grandfather ended up raising him, teaching him how to read through comics.
