The film tells the story of the situation after World War I, when the newly established state of Latvia had to engage in a political and military struggle for its existence. The support of the Western allies (Great Britain, France, and the United States) played a significant role in Latvia's struggle for independence. Great Britain was the first to get involved in the fight for Latvian independence, with its warships reaching the Latvian coast in December 1918. The film's script is based on historical documents, including reports to the British government on the situation in Latvia by Austin Keenan, head of the British military mission, and British diplomat Herbert Grant Watson, as well as other historical evidence. The film's visual narrative consists of reenactments, photographs, and newsreels.
