The lauded film about Alan Turing who created a machine to crack the continuously changing Enigma code of the Nazis and thus devising the first computer.
British intelligence agencies gathered the best decoders, linguists and mathematicians to crack the Nazi code so they could be a step ahead and win the war. This was quite a task and Turing came up with the idea to not try to crack the code and having to do the same the next day when the code was changed, but to make a machine that figures out the settings that the Nazis changed every day.
The director turned the story of the troubled Turing into a nicely developing film.
