At the end of “Insurgent,” Tris Prior (Shailene Woodley) discovered there was, indeed, life outside the enclosed walls of a post-apocalyptic Chicago where residents had long been separated into five factions—the selfless Abnegation, the peaceful Amity, the truthful Candor, the intellectual Erudite, and the courageous, death-defying Dauntless. As it turns out, this whole separatist existence was an experiment with aims to rebuild harmony in a world destroyed. Their hoped-for saviors? The rarified, strong-willed Divergents—those carrying all five groups’ attributes—for which Tris and boyfriend Four (Theo James) are a part. With the factions and Kate Winslet’s deadly, dictatorial Erudite leader Jeanine no more, Tris hopes they are finally on their way toward peace and truth. Hope quickly diminishes when Four’s formerly factionless mother Evelyn (Naomi Watts) demands the Chicago borders be sealed and starts holding trials of execution for Jeanine’s guilty followers. A plot is quickly put into action to breach the wall and find out if anything has survived on the other side, but the society that awaits them at David’s (Jeff Daniels) deceptively well-meaning Bureau of Genetic Welfare may be even more dangerous than what Tris and Four have just escaped.
