Eddie Izzard, Judi Dench, James D'Arcy and Jim Broadbent star in this British spy thriller set on the cusp of WWII, based on a true-life story. In the summer of 1939, influential families in Nazi Germany have sent their daughters to a finishing school in an English seaside town to learn the language and be ambassadors for a future looking more and more National Socialist. A teacher there sees what is coming and is trying to raise the alarm. But the authorities believe he is the problem.
