The Stranglers of Bombay (1959)

"This is true! This is real! This actually happened!"

In 1826 British-ruled India, the secret Cult of Thugee demonstrates their worship of their goddess, Kali, by the mutilation and mass murder of thousands of Indians while pirating the shipments of the British East-Indian Tea Company. As the British military leaders play down the implications of the piracy and disappearances, a lone captain realizes that they are not just coincidence and sets out to uncover the source of the deviltry, at the risk of his career. Based on history.
