The events of the film occur during the initial implementation of President Nixon's policy of Vietnamization, which called for US troops to turn over the war effort to the South Vietnamese Army. Caught in that transition, Firebase Kate receives no support from the South Vietnamese troops in the area, leaving them severely outmanned and outgunned, and in imminent danger of being overrun. Their only option is a desperate late night escape and evasion through a jungle filled with NVA soldiers.
