In Southeastern Iraq, a war-wearied National Guard unit has just received the exhilarating news that they are about to be 'demobilized' - finally sent back home to the safety of Spokane. But when they head out on one final humanitarian mission in the nearby town of Al Hayy, things go terribly wrong. Ensnared by insurgents, a ferocious and chaotic firefight ensues - from which none of the group will escape unscathed. Back in Spokane, the soldiers find themselves still reeling from the ambush's lasting effects - haunted by their own personal demons and feeling a deep disconnect between themselves and those leading everyday American lives around them. The heroic medic Will Marsh saved countless lives in Iraq, but when he tries to go back to being a regular dad, husband and doctor again, he finds he's unraveling inside. The once ultra-confident Vanessa Price, fresh out of rehab, faces the toughest challenge of her young life: learning to be a single mom with a single hand. Meanwhile, Private Tommy Yates returns with his best friend Jordan and Jamal Aiken discovers that a split-second, deadly shooting during the Al Hayy battle has sent his life at home spiraling into mayhem. Both heartbreak and heroism emerge as the four each find their own way - whether tragic or triumphant - to a reckoning with that fateful day in Iraq.
