Tris transmits a message to the whole city, revealing to them the existence of the Bureau and that Chicago was an experiment of the Pure. Her message to the Bureau is that Chicago is no longer their experiment, but the home of its citizens. Caleb detonates the explosives at the end of the message, tearing a massive hole through the cloak wall and revealing the two cities to each other. The film ends with the Chicago characters gazing at the Bureau in the distance, with David standing behind Tris via his machine, glaring at her.
