May 8, 1945: as London celebrates the end of war in Europe, the 19-year-old Princess Elizabeth (Gadon) and her 15-year-old sister, Princess Margaret (Powley), slip out of Buckingham Palace, and into the crowds, to party. Unrecognised, a night of excitement, danger and romance beckons.

Director Julian Jarrold (Becoming Jane, Brideshead Revisited) marks the 70th anniversary of VE Day with a fictionalised account of a right royal adventure, a historical drama inspired by truth.

Co-staring Emily Watson and Rupert Everett as the Queen Mother and King George VI.
