A group of top female agents from American, British, Chinese, Colombian, and German government agencies are drawn together to try and stop an organization from acquiring a deadly weapon to send the world into chaos.

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.
