Tobias, Tris, Christina, Cara, Uriah, Tori, Peter, and Caleb escape the city. Tobias and Zeke break Caleb out of his holding cell before they leave. Tris volunteers to go on one condition: that Caleb is taken with them. The Allegiant, led by Cara and Johanna, plan to send a group outside the city to find the truth about their existence and way of life. Tobias informs Tris that Caleb was decided to be a traitor and sentenced to be executed in two weeks. Caleb's betrayal, still fresh in her mind, prevents Tris from completely forgiving her brother. Meanwhile, Tris' brother Caleb is put on trial for assisting former Erudite leader Jeanine Matthews. Tris questions Evelyn's motives and is kidnapped by the Allegiant - a rebel group determined to escape the city and reinstate their old way of life - who invite her to a meeting the following night. Tension between the factionless and former faction members escalates, culminating in a deadly fight over the bowls used at the faction Choosing Ceremony. Factionless leader Evelyn Johnson appoints herself leader of the city, forcing people to operate under her command and live as factionless citizens. The video revealed the truth about the faction system and announced that the Divergent are needed outside the borders of the city.

Tris is shocked by the video released by Tobias to the public at the end of the raid on Erudite headquarters.
