It's the year 1915, and the British and Ottoman Empires are locked in a deadly struggle in the Middle East.
Commander of a unit of irregular horse, Major Andrew Selkirk lands on the coast of Palestine to retrieve a spy named Abraham. With the enigmatic Rachel as his translator, Selkirk discovers that the Turks have captured Abraham and finds himself involved in a power struggle, as both the Germans and Ottomans hope to bring Afghanistan and Persia to war against Great Britain.
Fighting a personal feud with a vengeful German, Selkirk leads his men across strife-torn Palestine, a land that everybody seems to claim as their own.
