In the futuristic city of dystopian Chicago, society is divided into five factions: Abnegation (the selfless), Amity (the peaceful), Candor (the honest), Dauntless (the brave), and Erudite (the intellectual). The remaining population are the Factionless, who have no status or privilege in this society. When children reach the age of 16, they undergo a serum-induced psychological aptitude test which indicates their best-suited faction, but they are allowed to choose any faction as their permanent group at the subsequent Choosing Ceremony.
