During the
British Raj, Captain Carruthers works under cover to track smuggled shipments of arms on the restless Northwest Frontier of India, the modern day Afghanistan-Pakistan border (the
Durand Line). He fears a full-scale rebellion is brewing. To forestall this, the British governor signs a treaty with the friendly, peace-loving ruler of Tokot, a key kingdom in the region, which is described as four days' march northward from
Peshawar. Meanwhile, the king's son, Prince Azim, befriends Carruthers and a British drummer boy, Bill Holder, who teaches him how to play the instrument. However, the king's brother, Prince Ghul, has the king assassinated and usurps the throne; Azim escapes a similar fate thanks to two loyal retainers. They hide in
Peshawar, where the British are based. When one of Ghul's men finds and tries to kill the prince, Azim is rescued by Carruthers' wife. Although he is offered sanctuary, Azim declines, believing it to be safer to remain hidden among his own people. Carruthers is then sent to negotiate with Ghul, who pretends to want to honour the treaty. In reality, Ghul is the mastermind behind the rebellion. He plots to kill Carruthers and his detachment of men on the last day of a festival to signal the start of the revolt. Prince Azim learns of the ambush. When he is unable to convince the governor, he chooses to risk his own life to warn his friends. After Azim leaves for home, the governor receives confirmation of the plot and sends four battalions to the rescue. Azim manages to warn Carruthers of the impending massacre by playing a warning signal he had learned from Bill on the "Sacred Drum of Tokot", saving many British lives. Ghul is killed in the ensuing battle and Azim is installed as his replacement. ==Cast==
