The first official trailer for the third film installment of "The Divergent Series," entitled "Allegiant," has been released on Buzzfeed, and stars Shailene Woodley and Theo James are more badass and intense than ever before.

Watch as Tris (Woodley) and Four (James) venture away from their walled-in world in Chicago into the dangerous world on the other side of the wall with super advanced technology. The action-packed trailer shows Tris and Four fighting against The Bureau of Genetic Welfare, the organization that is run by Jeff Daniels and responsible for placing them in a "safe place," otherwise known as Chicago. They quickly learn that the only world they have ever known for their entire lives was just an experiment, and it's up to them to save all their friends as the Bureau tries to destroy Chicago.

"People think walls separate us, but they also protect us," Naomi Watts' character says. "Those people out there kept us in a cage for 200 years. That is not someone I want to engage with."

"The Divergent Series" films are based off of the worldwide best-selling trilogy by Veronica Roth. "Allegiant" will be part one of the final book, with part two, which has now been named "Ascendant," to follow soon after.

"The Divergent Series: Allegiant" hits theaters March 18, 2016.
