Through a set of unexpected techniques, and as a result of an unlikely friendship, Bertie is able to find his voice and boldly lead the country into war.

This documentary tells the story of the man who overcame his own failings for the sake of his nation. When his older brother, Edward VIII, abdicated the throne to marry Wallis Simpson, nervous-mannered successor George "Bertie" VI was plagued with shyness and a speech impediment when speaking to his subjects. An introvert as well as a humble man, events and circumstances resulted in him becoming an inspiration for the British nation during its war with Germany.
