Adapted from author Philippa Gregory's historical novel of the same name, director Justin Chadwick's atmospheric period drama follows the fierce competition between sisters Mary (Scarlett Johansson) and Anne Boleyn (Natalie Portman) to win the affections of Tudor king Henry VIII (Eric Bana). Anne and Mary Boleyn are under pressure from their father and uncle to help maintain the family's rich legacy and ensure their further prosperity by winning the affections of none other than the king of England (Eric Bana). But life in the royal court is far different than it was in the countryside where these two sisters were raised, and before long their bid to earn the love of the king has transformed two once-happy sisters into bitter rivals. At first, it appears that Mary has triumphed in winning the king's favor by becoming his mistress and bearing him an illegitimate child. Despite her early success, however, Mary has underestimated just how clever and cunning her sibling can truly be.
