Early 18th century.
England is at war with the French.
Nevertheless, duck racing and pineapple eating are thriving.
A frail Queen Anne (Olivia Colman) occupies the throne and her close friend Lady Sarah (Rachel Weisz) governs the country while tending to Anne's ill health and mercurial temper.
When a new servant Abigail (Emma Stone) arrives, her charm endears her to Sarah.
Sarah takes Abigail under her wing and Abigail sees a chance at a return to her aristocratic roots.
