In a stark departure from her breakthrough role as Bella in Twilight, Kristen Stewart plays a conflicted soldier in the second trailer from IFC Films' Camp X-Ray.

Kristen Stewart stars as Amy Cole, a young woman who joins the military to be part of something bigger than herself and her small town roots. But she ends up as a new guard at Guantanamo Bay instead, where her mission is far from black and white. Surrounded by hostile jihadists and aggressive squadmates, she strikes up an unusual friendship with one of the detainees. A story of two people, on opposite sides of a war, struggling to find their way through the ethical quagmire of Guantanamo Bay. And in the process, they form an unlikely bond that changes them both.

Peyman Moaadi co-stars as Ali Amir, the young detainee whom Amy forms a bond with, alongside a supporting cast that includes Yousuf Azami, Tara Holt, Lane Garrison, John Carroll Lynch and Julia Duffy in Camp X-Ray, which marks the writing and directing debut of filmmaker Peter Sattler.
