The book Allegiant is written from the perspective of Tris and Tobias. News comes and the Divergent are wanted out of the city. The leader of the Factionless, Evelyn Johnson, wants to be leader of the city. She also wants everyone to live under her rules and act as equal factionless citizens. Factionless and former faction members do not get along at all. Evelyn ends up getting kidnapped by the Allegiant who want to leave the city and re-start their old way of life.
Tris’ brother, Caleb, is put on trial for helping Jeanine. Tris doesn’t forgive her brother for his betrayal even though he’s sentenced to death. The Allegiant plan to send a group outside the city and Tris volunteers to go if Caleb goes also. Tobias breaks Caleb out of jail and they leave with Tris, Christina, Cara, Uriah, Tori, and Peter. While driving they meet a woman named Zoe and a man named Amar. Zoe and Amar take the group to the Bureau of Genetic Welfare, where they meet Tori’s brother and are tested to verify and study their Divergence. Tris learns that she is truly Divergent but Tobias learns that his genes are still ‘damaged’. Tris is taken to David, the leader of the Bureau, to find out about her mother. He gives Tris her mother’s journal.
Nita, who is also genetically damaged, asks Tobias to join her rebellion. She tells him that the Bureau is lying to everyone and she intends to demonstrate that the genetically pure are flawed as well. Nita and her allies attack the compound and Tris saves David from being shot by Nita. She stops the attack and Nita is placed in prison.
After the attack, Tris becomes a member of the Bureau’s council. In her position, she is told about the events taking place in the city. David decides to use the memory serum to wipe the memories of the people in the city. Already angry about what David wants to do, Tris also learns that the Bureau created the serums which led to the destruction of Abnegation and the enslaving of the Dauntless. Tris and her friends begin to create a plan to save her city. The group decides to break into the Weapons Lab and use the memory serum to wipe the memories of the Bureau. They learn that the lab is protected by a death serum. Caleb volunteers to break into the lab and asks Tris if it will make her forgive him for everything he has done. She says yes.
Tobias, Christina, Peter, and Amar plan to go into the city to protect their loved ones against the serum. Christina gets serum doses that will counteract the memory serum. The group plan to inject themselves with it. Tobias notices that Peter only pretends to inject himself with the inoculation serum. Peter wants his memory to be erased. Christina gives an extra vial of the memory serum to Tobias. He is supposed to use it against either Marcus (his dad) or Evelyn (his mom) in an effort to end the conflict in the city. Tobias meets with his mother and asks her to drink the serum to end the fighting and become his mother again. She refuses. They meet with Johanna and Marcus to iron out an end to the conflict. On the way out of Erudite headquarters, Peter wants to take the memory serum to become a new person. Tobias gives Peter the serum, erasing his mind for good.
Tris decides to carry out the mission instead of allowing Caleb to do it. She hopes that her resistance to serums will include the Death variant. Tris destroys the entrance to the Lab and is exposed to the death serum, but she survives. At the lab, David tells Tris that he noticed she was colluding with the genetically damaged. Since he is determined to keep the order, David shoots Tris. She still manages to release the memory serum. After being shot by David, Tris sees her mother reach out for her and she accepts her mother’s embrace. Tris succumbs to her wounds and dies. Tobias, Peter, and Christina return to the compound and are told about Tris’ death. Tobias is angered by the fact that Tris died for Caleb even after his betrayal. Caleb tells Tobias that Tris never wanted to leave him. Uriah, who has been shot, was taken off of life support and Tobias blames himself for Uriah’s death. He returns to his home in the old Abnegation sector and cuts his hair. Tobias decided to use the memory serum on himself to forget Tris and Uriah. Christina convinces him not to use it for Tris’ memory sake. Tobias agrees and decides against it. Two and a half years later, former faction members, factionless, compound members, and other outsiders move in and out of Chicago. The city is at peace. Tobias accepts everything he has been through and reflects on his belief that while life damages everyone, over time people can always be mended.
