Before the sun can set on Jack Drummond's career as a pilot in the British Navy, he must complete one final flight - a weapons drop over Tibet to aid guerilla fighters in their border dispute with the Red Chinese. But before he can complete the job, his plane and supplies are burned, stranding him in the Himalayas. Now, with his plane grounded, he must deliver a Tibetan leader's son to safety over land. With the advancing Chinese enemy hot on his heels, Drummond's final mission becomes a suspense-filled struggle for survival across the world's most rugged terrain. But first he must uncover the truth behind the murderous conspirators - before they can kill him.
