 Congotanga, West Africa, has no extradition laws; the government is controlled by foreign gangsters, headed by Carl Rittner. The latest plane from Europe carries lovely Louise Whitman, fleeing a French murder charge, and Mannering, who pays resident hit man O Connell to kill her. Through a chain of circumstances Louise, O Connell, and heroic surveyor David Carr end up alone in the jungle on Carr s mission to determine the true border of Congotanga... in which Rittner is keenly interested.
