Red Joan (DVD 2018)

Joan Stanley is a widow living out a quiet retirement in the suburbs when, shockingly, the British Secret Service places her under arrest. The charge: providing classified scientific information, including details on the building of the atomic bomb, to the Soviet government for decades. As she is interrogated, Joan relives the dramatic events that shaped her life and beliefs: her student days at Cambridge, where she excelled at physics while challenging deep-seated sexism.
