North West Frontier (1959)

In northwestern India soon after the turn of the 20th Century, Moslem rebels seek to kill a six-year-old Hindu prince to end his family line. Captain Scott of the British Army is ordered to get the prince out of the region safely. Adventure ensues as Scott sneaks the child away, through Moslem-held territory, by train. Also on board are the boy's American governess, an arms merchant, a cynical reporter, and two upper class Britons.
