Based on the real life story of legendary cryptanalyst Alan Turing, the film portrays the nail-biting race against time by Turing and his brilliant team of code-breakers at Britain's top-secret Government Code and Cypher School at Bletchley Park, during the darkest days of World War II.
Struggling to survive in post-WWI Copenhagen, a newly unemployed and pregnant young woman is taken in by a charismatic elder to help run an underground adoption agency. The two form an unexpected bond, until a sudden discovery changes everything.
