Divergent runaway Tris (Shailene Woodley) is faced with the possibility of a safer kind of life in this very intense final trailer for the sci-fi flick The Divergent Series: Allegiant. David (Jeff Daniels), the leader of the Bureau of Genetic Welfare, believes Tris isn't Divergent at all, but rather, genetically pure. A "miracle," in fact. And everyone who isn't Divergent is damaged. Now it's the "pure" against the "impure" in this latest epic installment of the series, forcing our heroine Tris to stop yet another potential genocide of the human race.The Divergent Series: Allegiant hits theaters March 18.
