The final trailer for "The Divergent Series: Allegiant" has finally arrived. The video highlights Tris' (Shailene Woodley) fight against Jeff Daniels' David, head of the Bureau of Genetic Welfare, and his crazy plans. "To your people you're a divergent. To me, you are a miracle. You're genetically pure," he tells Tries. He adds that the rest, including Four (Theo James), are damaged and Tris is "the only one worth saving."

As David's opinion somehow suggests eradication of humanity, Tris doesn't agree with him. "Everybody's worth saving," she tells Four. So they along with her brother Caleb (Ansel Elgort), their friends Christina (Zoe Kravitz) and Peter (Miles Teller) take a stand against the organization.

"Allegiant" takes Tris and Four into a new world, far more dangerous than ever before. After the earth-shattering revelations of "Insurgent", Tris must escape with Four and go beyond the wall enclosing Chicago. For the first time ever, they will leave the only city and family they have ever known.

Once outside, old discoveries are quickly rendered meaningless with the revelation of shocking new truths. Tris and Four must quickly decide who they can trust as a ruthless battle ignites beyond the walls of Chicago which threatens all of humanity. In order to survive, Tris will be forced to make impossible choices about courage, allegiance, sacrifice and love.

Robert Schwentke returns as director for the third installment of the "Divergent" movie series, which is set to open wide in the U.S. on March 18.
