The Counter Assault Tactical (C.A.T.) Squad investigates a spy who is supplying plutonium to the Sjambok, a racist South African paramilitary group that is working on a nuclear bomb. The American government, too, is investigating Sjambok, using the top-secret spy plane Python Wolf. When one of the members of the C.A.T. Squad is shot down over South Africa during another mission, his squad leader undertakes a rescue operation to bring his friend back home.
