In March 2018, amidst the War in Afghanistan, U.S. Army Special Forces Master Sergeant John Kinley and his unit are ambushed by a truck bomb attack orchestrated by the Taliban during a routine vehicle inspection at Lashkargah, which claims the life of his interpreter.

During another raid to check for a possible insurgent arms cache about 100 kilometres (62 miles) north of Bagram Air Base, Kinley's unit is attacked by Taliban reinforcements, who kill everyone except for him and Ahmed.

Whilst attempting to return to the airbase by navigating through the mountainous Afghan terrain, they are once again ambushed by insurgents, who manage to wound Kinley, before clubbing him with a rifle butt, incapacitating him.

Emotionally tormented and rendered near sleepless by his inability to repay his indebtedness towards Ahmed, Kinley finally resolves to save him himself, enlisting the assistance of his superior, Lieutenant Colonel Vokes, to procure the visas.

Returning to Afghanistan under the alias of Ron Kay, Kinley meets with Parker, a private military contractor, who promises to provide support on the condition that the former locates Ahmed first.

Meanwhile, Parker deduces Kinley's true identity; realizing that the duo is in danger due to their value to the Taliban, he arranges for an AC-130 gunship and an Apache attack helicopter to provide air support.
