U.S. Army Sergeant Edward Brockman is stationed at
Camp Humphreys in
South Korea. His commanding officer has assigned him with Corporal Stephaine Selby to repair a ground-penetrating radar (GPR) unit near the
Korean DMZ. Brockman pilots the team consisting of Josh Weaver, a civilian tech-support specialist, Chris Lebold, Jonah Ross, and Selby to fly close to the border between
North Korea and
South Korea. Brockman takes his team to the DMZ and repairs the unit. Upon returning, extreme winds and lightning storms cause the helicopter to malfunction, forcing it to crash deep within North Korean territory. Brockman, Selby, Weaver, Ross, and the pilot, Milner, survived the crash, but Milner was severely wounded. They try to call in for help, but the U.S command is unable to send a medevac for the team because they just crashed in North Korea, which is beyond any friendly airspace, so they will have to rendezvous at the DMZ. Pursued by the
KPA, the team treks through rough terrain and stumbles upon a village barn, where they are confronted by a farmer and his family. Milner succumbs to his injuries. They bond with the farmer's family and their daughter. While they rest at the barn, the KPA forces arrive to investigate the soldiers' whereabouts, forcing the team to leave. Selby is left behind and hides beneath a floorboard as the authorities search the barn. The officer discovers Milner's body and executes the farmer and his wife for hiding the soldiers, forcing Brockman and his team to kill the patrol. They steal the patrol's truck to get back across the DMZ, taking the farmer's daughter with them. A patrol car stops them, forcing the team to engage, though Weaver was killed during the shootout. Through the GPR unit, Brockman discovered an underground mine shaft that runs under the border, so he takes his team down there to escape through South Korea. As they navigate the tunnels, North Korean soldiers pursue them. They endure a heavy firefight with the soldiers until they are running out of ammunition, so Brockman covers his team while they retreat to the border. U.S.
Delta Force arrives with reinforcements to drive the North Koreans back, forcing them to retreat while they take the wounded Brockman away to safety. The team boards the helicopter and returns to base to get some medical attention. ==Cast==
