“12 Strong” is set in the harrowing days following 9/11 when an elite U.S. Special Forces unit, led by their Captain, Mitch Nelson (Hemsworth), is chosen to be the first U.S. soldiers sent into Afghanistan for an extremely dangerous mission in response to the attacks. Leaving their families behind, the team is dropped into the remote, rugged landscape of northern Afghanistan, where they must convince General Rashid Dostum (Navid Negahban) to join forces with them to fight their common adversary: the Taliban and their Al Qaeda allies.
