In nineteenth-century India, a murderous cult runs rampant, killing thousands of unwitting travelers and stealing their goods. The British East India Company decides to act, hiring the newly arrived Captain Connaught-Smith (Allan Cuthbertson) instead of Captain Lewis (Guy Rolfe), who knows the area and the people well. Frustrated with Connaught-Smith's methods, Lewis decides to investigate on his own, leading to information that may take down the dastardly cult once and for all.
