A new trailer for Summit’s Allegiant has dropped, so prepare for plenty of teenage angst and post-apocalyptic struggle as the series begins its final chapters. The third installment of Veronica Roth’s Divergent novels, Allegiant brings us to the bonkers left turn the series took in the final book. Picking up after 2015’s Insurgent, Tris (Shailene Woodley) and Four (Theo James) escape the wall around Chicago, finding themselves in a dangerous and highly advanced society that has been monitoring them the whole time. Faced with the looming death of their friends and enemies alike, Tris and Four must now decide who they can trust as a battle threatens all of humanity. The film hits theaters March 18, 2016.

Following the path blazed by Harry Potter and The Hunger Games, Allegiant is part one of a two-part finale, based on just the first half of the book of the same name. The follow up, entitled Ascendant, adapts the second half and is due in 2017. In addition to Woodley and James, Allegiant stars Jeff Daniels, Octavia Spencer, Miles Teller, Ansel Elgort and Ray Stevenson, among others. Robert Schwentke directs from a script by Noah Oppenheim, Adam Cooper, Bill Collage, and Stephen Chbosky. Douglas Wick, Lucy Fisher, and Pouya Shahbazian produce.
