The President's daughter, unable to experience life like a normal 18 year-old, escapes from her entourage of Secret Service agents while traveling in Europe. She falls in love with a handsome British stranger, who also happens to be working undercover for her father.
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.
