A United Kingdom

The film is based on the true story of the heir to the throne of Bechuanaland, (present day Botswana), Seretse Khama of the Bamangwato people, who studies law in London immediately after World War II.

There he meets an Englishwoman, Ruth Williams, whom he eventually marries, despite the protests of both their families and opposition from the British government, which is concerned about relations with South Africa and the stability of the entire region.
