The Green Goddess(1930)
An airplane carrying three Brits--Major Crespin, his wife Lucille, and Dr. Trahern--crash lands in the kingdom of Rukh. The Rajah holds them prisoner because the British are about to execute his three half-brothers in neighboring India. His subjects believe that their Green Goddess has given them the lives of the three Brits as payment for the lives of the Rajah's brothers. They will execute them when the brothers are executed. Trahern and the Crespins must figure a way to use the Rajah's radio to call India for help.
