Escape to Burma is a 1955 American Technicolor adventure film directed by Allan Dwan starring Barbara Stanwyck, Robert Ryan and David Farrar.
In the 1920s, British Burma, the son of a local ruler, the Sawbwa, was killed - apparently by his European mining partner, Jim Brecan.
Brecan flees through the jungle with a bag of rubies from the mine and reaches the estate of Gwen Moore, who uses elephants to harvest teak.
After he helps her deal with some problems, including a killer tiger, she makes him her manager.
The prince had the plague and, in his delirium, was about to expose a village to the disease, forcing Brecan to shoot him.
