The leader of an African nation wants to build a new dam to strengthen his nation's economy. The tribes in the flooded area protest to him, but he ignores them; as a result, they declare war. Instead of using his army to suppress the demonstration and prevent negative press, the president employs four foreign mercenaries to track down the tribe's leader, Kuruba. However, Vietnam veterans T.J. and Cliff discover how they are being used and change their minds after learning the tribes' motivation.
