A hotshot, wisecracking New York newspaper reporter, teams up with his crippled Army buddy Steve and sexy pilot Anne in Argentina to find an airplane called Condor rumored to have been carrying Chinese treasure when it crashed into a glacier forty years earlier.

In the deepest, most remote part of the Amazon, a treasure is hidden! A treasure so valuable that men would kill for it, women would undress for it, and entire armies would fight for it !

After their mission is overrun by North Vietnamese forces, a missionary couple, their Australian guide, a South Vietnamese major, a brothel owner and her daughter all get in the mission's battered school bus and try to make their way to safety. Soon after leaving, however, their bus is commandeered by three US Marines trying to get back to their base at De Nang. To reach their destination, they must fight through most of the North Vietnamese army.
