The story takes place in England in the early eighteenth century. Anne (Olivia Colman) is the Queen of Great Britain. She has been maintaining a secret lover relationship with her childhood sweetheart, Duchess Sarah (Rachel Weisz). Abigail (Emma Stone) is a distant relative of Sarah. She has always been eager to integrate into the upper class represented by the royal family. She came to Sarah and wanted to get a job, but Sarah was very cold to her. With her intelligence and strategy, Abigail attracted the attention of Queen Anne and was able to serve her. Soon, Abigail learned the "little secret" between Queen Anne and Sarah. Abigail, who was full of desire for power and conspiracy, began to hope that she could replace Sarah and get the favor of the queen.
