From IMDB:

In early 18th century England, a frail Queen Anne occupies the throne and her close friend, Lady Sarah, governs the country in her stead. When a new servant, Abigail, arrives, her charm endears her to Sarah.

Based on historical facts,  this two hour film set in England in the early 18th century presents a battle between Lady Sarah and Abigail for the affections of Queen Anne.

Olivia Coleman, who played D.S. Ellie Miller in Broadchurch, portrays the sickly Queen Anne as a somewhat repellant and incompetent Queen.  Rachel Weisz plays Lady Sarah Churchill who was the Duchess of Malborough. Lady Sarah is portrayed as Queen Anne’s lesbian lover and the real power behind the throne. At one point her impoverished cousin Abigail appears on the scene looking for employment. Through clever personal competition and intrigue Abigail, played by Emma Stone,  rises to eventually replace Sarah. Since this is history I am not spoiling the plot here. In fact the entire point of the story is how Abigail tricks her way to the top.

WARNING: Although I started by disliking the film and then found it disgustingly fascinating, Kathy did not enjoy watching.  If there is any historical accuracy in the film then the English nobility were debauched and imperious lechers.  Brace yourself for nudity, sexual assaults on servants, and continuous use of the C  _ _ T word.

In its favor, the photography, the costumes, and the palace rooms are feasts for the eyes. Never mind the vomit.
