The city is a large, circular quarintined area split into five parts, one for each faction. Aquiring help from the force that is trying to restore factions in the city, the Allegiant, Beatrice, Tobias, Claire, Uriah, and few others are able to escape the city and migrate to the real world. Looking around, they see signs of rebuilding from some devestation. As the characters find civilization at a scientific compound, where the leaders of the country try to explain what had happened, they notice that many of the people living there have tensions between each other. Finding this, Tobias ventures to the fringe. The fringe is a desolate place where outcasts and rebels go to live and hide. Exploring the new and dangerous place, Tobias is made aware of a new rebel force against the government,
It is up to Beatrice and Tobias to decide weather to trust these rebels, or to side
with the government in the next part of Allegiant.
