If you’re unfamiliar with Alan Turing and his incredible contributions to the war, The Imitation Game lays it all out, detailing his early life, his pivotal role in cracking the German’s Enigma machine, and his horrendous treatment by the British government in the years following the conclusion of World War 2.
The narrative begins as Turing is recruited by Commander Alastair Denniston to join a team of cryptographers analyzing Nazi coded messages. The messages, sent by the Enigma machine, are nearly impossible to crack, though Turing’s brilliant number-crunching mind is considered the last-ditch effort to figure it out.
