When a plane carrying an atomic warhead crashes on a South Pacific island, Steve is sent to retrieve it, but finds that an ex-Japanese Zero pilot, Kuroda, has taken it to his home. Steve must successfully navigate his way through the booby-traps and get the warhead before a rogue guerrilla group does.

When Kuroda is asked to track down a wolf boy roaming the island forests of Hoyoko, Japan, he asks for only one man to help him: his friend Col. Steve Austin.

Steve and Rudy go to check up on scientist, Cheryl Osborne, who was performing research on chimpanzees but who has ceased communications. When they arrive they find something has destroyed the lab, and Rudy is bitten by a rampaging chimpanzee. Rudy begins to turn psychotic and Steve must both stop him and find Osborne before it's too late.

An Indian Chief who is also a trained scientist discovers an ore on the reservation that can be a great source of power. So Oscar sends two men to check it out but they vanish. So he sends Steve to find them. But the tribe's medicine man who is very traditional refuses to grant Steve permission to go there because it's sacred ground. But there's a test which is very grueling, if he passes he can enter. But the medicine man has other plans.
