La chatte sort ses griffes (1960)

No, Cora Mennessier (also known as "Chatte") is not dead. Condemned to be shot for being a traitor to the French Resistance, she has survived her execution by "Le Capitaine". Unfortunately, she is immediately captured by the German forces, imprisoned and brainwashed. Her "mission" is now to contact the leader of the local Resistance movement and to gather information before handing it over to her manipulators. But have they really managed to make her a puppet on a string?
