Based on NYT bestselling book 'The Angel: The Egyptian Spy Who Saved Israel' by Uri Bar-Joseph.

In 1894, French Captain Alfred Dreyfus, a young promising officer, is degraded for spying for Germany, wrongfully convicted of treason and sentenced to life imprisonment at Devil's Island. Among the witnesses to his humiliation is Georges Picquart, who is promoted to run the military counter-intelligence unit that tracked him down. But when Picquart discovers that secrets are still being handed over to the Germans, he is drawn into a dangerous labyrinth of deceit and corruption that threatens not just his honor but his life.

In the beginning of WWII, with Britain becoming desperate, Churchill orders his new spy agency -- the Special Operations Executive (SOE) -- to recruit and train women as spies. Their daunting mission: conduct sabotage and build a resistance. SOE's "spymistress," Vera Atkins (Stana Katic), recruits two unusual candidates: Virginia Hall (Sarah Megan Thomas), an ambitious American with a wooden leg, and Noor Inayat Khan (Radhika Atpe), a Muslim pacifist. Together, these women help to undermine the Nazi regime in France, leaving an unmistakable legacy in their wake. Inspired by true stories.

A British diplomat travels to Munich in the run-up to World War II, where a former classmate of his from Oxford is also en route, but is working for the German government.
