German soldier Stefan Brandt is on a mission to investigate exiled German Monarch Kaiser Wilhelm II. The Kaiser lives in Huis Doorn, a secluded mansion just outside of Utretcht, the Netherlands, and it’s under siege from an invading Germany. The country’s authorities are concerned that Dutch spies may be watching the Kaiser. As Brandt begins to infiltrate the Kaiser’s life in search of clues, he finds himself drawn into an unexpected and passionate romance with Mieke, one of the Kaiser’s maids, whom Brandt soon discovers is secretly Jewish.
When Heinrich Himmler, Head of the SS, decides to come for an unexpected visit with a large platoon of Nazis in tow, the stage is set for a breathtaking showdown as secrets are revealed, allegiances are tested, and Brandt is forced to make the ultimate choice between honouring his country and following his heart.
