In the midst of World War II's turmoil, the quaint British town of Bury St. Edmonds becomes a focal point where lives intersect and secrets unravel. An 18-year-old woman finds herself caught in the throes of a great wartime secret – the breaking of the German Enigma code. Her recruitment into the "Ultra" program brings her to the heart of Bletchley Park's most clandestine operations, where Alan Turing and his team forge the world's first computer in a bid to crack the ever-changing German codes. Every day, she grapples with the weight of the secret, so profound that even her family is oblivious to her covert role. Meanwhile, she captures the heart of an assertive American soldier and their whirlwind wartime romance culminates in a heartwarming union, facing the challenges of the Official Secrets Act. The soldier, persistent and deeply in love, goes to great lengths, in order to secure her release from the program and to solidify their commitment to one another.
