In 1965, while bombing Laos in a classified mission, the propeller plane of the German-American US Navy pilot Dieter Dengler is hit and crashes in the jungle. Dieter is arrested by the peasants, tortured by the Vietcong and sent to a prisoner camp, where he meets five other mentally deranged prisoners and guards. He becomes close to Duane and organizes an escape plan; however, the unstable Gene opposes to Dieter's plan. When they discover that there is no more food due to the constant American bombings in the area and their guards intend to kill them, Dieter sets his plan in motion. However, an unexpected betrayal splits the group and Dieter and Duane find that the jungle is their actual prison.
