The Concert Party are on their way to put on a show for the troops at Bannu, on the Northwest Frontier. After a long, hot train journey, they set off by road on the last leg of the journey. The truck breaks down and the men are stranded. They find themselves surrounded by hostile tribesmen. Solly has to pose as Bing Crosby and put on a show for the tribesmen in order to pacify them. When Gloria appears as Dorothy Lamour, the leader of the tribesmen wants to buy 'her'.
