Based on the novels of Veronica Roth, the series describes a dystopian future where society is broken into factions that all must conform to. But some don't fit into any faction.
In a dystopian Chicago, a future society is divided into five distinct and different factions based on human traits, and a 16-year-old girl leaves her own faction to join a rival one, upsetting the delicate balance that the rigid culture deems dangerous.
Five days after the assault on the Abnegation faction by Erudite's leader, martial law has been declared and Tris Prior must try to save those whom she loves, while trying to help maintain a tenuous balance between the waring factions, as she tries to come to terms with her Divergence.
Beatrice Prior and Tobias Eaton venture into the world outside of the fence and are taken into protective custody by a mysterious agency known as the Bureau of Genetic Welfare.
