This is kind of a cheesy biopic. The storyline is fascinating and is important, particularly given the success rate of 1 in 3 British covert spies in Nazi occupied France were exposed and perished, including being sent to Dachau, among other premature deaths. The acting of the lead is okay but not great. Stana Katic is amazing and I could watch anything with her in it and her portrayal of Vera Atkins was solid. Didn't know Linus Roache was an English actor since he played a role in one of my favorite spy shows, Homeland.
