MGM has debuted a new trailer for Guy Ritchies’ war zone-set thriller ‘The Covenant.’

The story follows US Army Sergeant John Kinley (Gyllenhaal) and Afghan interpreter Ahmed (Dar Salim). Kinley and Ahmed are the only survivors when their unit is ambushed on patrol. With enemy combatants in pursuit, Ahmed risks his life to carry an injured Kinley across miles of gruelling terrain to safety.

When Kinley learns that Ahmed and his family were not given safe passage to America as promised, he must repay his debt by returning to the war zone to retrieve them before the Taliban hunts them down first.

Alexander Ludwig, Antony Starr, Jason Wong, Bobby Schofield, Sean Sagar, Sina Parvaneh, Emily Beecham, Cyrus Khodaveisi and Christian Ochoa co-star alongside Gyllenhaal.
