Holt, Butler and Adams, survive a Viet Cong ambush and rescue two undercover American agents, named Hawkins and Jensen, whom are seeking out a mysterious Intelligence agent, known only as 'the General' who has classified documents detailing an illegal arms deal between a corrupt general, named Delevane based in the Pentagon, whom is involved in an arms-for-profit deal with a corrupt U.S. Army officer back in Vietnam, named Colonel Harker, who sends troops, led by Corporal Stringer, to look for 'the General'.
During this, Hawkins tells Holt that there will be an arms shipment to be made very soon which will go to the North Vietnamese for huge profit which will prolong the war for the military back home.
Hawkins and Holt are captured by another group of soldiers, led by a shady Australian named Lt. Smitty, who tries to find out which one of them is the General.
But Stringer is revealed to be a turncoat who is working with Butler, also an undercover agent, who wants to help stop the arms deal from happening which leads to Holt, Butler, Hawkins, Stringer, Smitty, Adams and Jensen to team up to launch an climatic attack against Harker's camp.
The film ends with a news report about a major American military offensive into North Vietnam related to the arms shipment, and the distraught Delevane commits suicide before he is to be questioned about his involvement in the deal.
