London, 1913. After bombing the Prime Minister’s house, suffragette Natalie Petrov is chased by the police. She is rescued by Lady Thompson, an aristocratic doctor who offers her a way out: Natalie will stay at the Thompson’s country house for six months, until her name vanishes from the ‘most wanted’ list. She agrees to work as a maid for Lady Thompson’s daughter, Elizabeth, a cold and distant socialite who doesn’t know Natalie’s true identity. However, the task becomes progressively harder as Natalie finds herself attracted to her mistress.
