Law of the Jungle

Nona Brooks, former member of a stranded theatrical troupe, earns a
temporary living singing in a café in Duakwa, British Rhodesia,
Africa. The café owner is secretly in league with two foreign
agents with a goal of making the natives restless. American explorer
Larry Mason leaves for the jungle with his servant, Jeff and a safari.
Nona escapes the café into the jungle but is followed by the agents
as, unknowing to her, she is carrying a report of the agent's
activities. She joins the safari just as all hands are captured by a
tribe of natives.
