A World War I British Army patrol is crossing the Mesopotomian desert when their commanding officer, the only one who knows their destination is killed by the bullet of unseen bandits. The patrol's sergeant keeps them heading north on the assumption that they will hit their brigade. They stop for the night at an oasis and awake the next morning to find their horses stolen, their sentry dead, the oasis surrounded and survival difficult.
