Quick recap
After the city's revelation, Chicago faces new conflicts. Evelyn closes the wall and puts Jeanine's allies on trial, while the Allegiants want to restore the factions. Tris and Four free Caleb and get over the wall with their friends. On the other side, technology they have never seen takes them to the Bureau of Genetic Welfare. Its leader, David, explains why Chicago existed and what he expects of Tris. She accesses her mother's memories, and Four senses the Bureau is hiding something. The two disagree on what to do, and Tris's decision could cost her the help of the one she loves most.
