English-born Joan Stanley (Dame Judi Dench), a Soviet and Communist Party sympathizer, becomes employed as a British government civil servant, and gets recruited by the K.G.B. in the mid 1930s. She successfully transfers nuclear bomb secrets to Soviet Russia, which enables them to keep up with the west in the development of atomic weapons, and remains undetected as a spy for over a half a century.

If you think you know all there is to know about the spy history since 1945, you will find this film pretty interesting and revealing. i have not heard about the ''granny spy'' until now and its a good melodramatic, historic flick, made for the newest generations.

judi dench does a remarkable appearance in this drama that jumps back and forth in history, the present is spun around police interrogation, and dialouges with her gobsmacked lawyer son, and the past where we follow the main from studies at cambridge into advancing into assistant at the nuclear research institute.

its has some romantic interludes here and there, the way they are made weakens the production, because its not profound enough . the score is classic style british drama series style of music, and gives a nice float to the motion.

its worth a glance thinks the grumpy old man if youre into the war and cold war history, and the keywords are like in many other features to forgive , bow and forget. recommended
