The remarkable story of two brothers and two women at the heart of the British monarchy.

On 11th December 1936, following the abdication of his brother Edward VIII, King George VI ascended to the British throne. The day marked the culmination of a crisis that had threatened to destroy the British crown and Empire. Never before had a British monarch voluntarily renounced their title. Edward did so in order to marry the woman he loved, Wallis Simpson. It would be left to the younger brother to restore the credibility of the world’s foremost constitutional monarchy; a feat George would have found impossible without the support of his ‘helpmate’ and wife, Elizabeth. It also marked the end of the fraternal friendship between Edward and George; one that would never be repaired – nor the players reconciled. Using archive footage combined with new interviews (including Royal biographer Hugo Vickers and the Countess Mountbatten of Burma), this film examines how, whatever their differences, the brothers looked for similar qualities in the women they loved but how this, in turn, set them apart and changed their relationship from one of love and loyalty to one of suspicion and betrayal.
