Mary Stuart became Queen of France at just 16, and a widow two years later. Instead of remarrying, she returned home to Scotland to claim her throne. Soon, England and Scotland both fall under the reign of Elizabeth I, and a struggle for power between the two women ensues.

The film is set for release through Focus Features on December 7. It also stars Jack Lowden, Joe Alwyn, Gemma Chan, Martin Compston, Ismael Cordova, Brendan Coyle, Ian Hart, Adrian Lester, James McArdle, with David Tennant, and Guy Pearce.
