Tris, Tobias, Christina, Caleb, and Peter sucessfully made it to the opposite side of the fence. the first thing they see is just green land. However, in a distance they notice a city. Considering the condition they are in, they decided to check it out. everything was Perfect.
After reaching the city, they are greeted with people wearing colorful clothing, knowing its the dress code. A few guards spot the newcomers and take them to the director of the city. to clear things up the director states that the factions are a experiment and is planning to recreate a new one.
Since Tris and her team have found their new home, the first priority is to start training. All members are indvidually trained, learning new techniques and about new technology along the way. Tris however overhears the director and some unfamiliar faces discussing something.
It turns out the discussion was a plan the director has on wiping the memory everyone inside and outside the fence to start a new experament. Tris warns everyone in danger, but fails as its too late. The directer finds out and plays a video both citys, hypnotizing everyone.
The only way to stop everyones memory from being erased is to stop the video from being played. Tris and Caleb rush to the control room as fast as they can, while the rest of them fight guards. What they dont know, is that the Director is after them too.
Finally reaching the control room, Caleb begins to stop the video. Unknowingly a knife is thrown right at him causing him to fall in pain. The Director and a two others walk in, grabbing Tris. The director pulls something out of his pocket. All thats known is a gun is pointed straight at her.
