London in the 1950s. Lottie is a reluctant typist at MI5 and the even more reluctant daughter of the organisation's most illustrious spy.

Together the two young lovers embark on a star-studded adventure through the glittering world of theatre - but, between missing files, disapproving parents, and their own burgeoning creative endeavours, life is about to become very complicated indeed...
