October 1914. Antwerp is under siege and two British spies, Captain Wendel and Lieutenant DeBoise, are caught up in the decimation of the city. While they look for an escape, Wendel and DeBoise are given a new mission: to rescue a member of the Belgian Royal Family who is not only trapped on the German side of the battle line near Ypres, but is also unwilling to cooperate in any rescue efforts.
The mission leads Wendel and DeBoise to face the full force of the German onslaught in the first battle of Ypres. Will the duo come out of it unscathed? And will they be able to get the cantankerous Belgian Royal out from the German side?
