Admiral (Адмиралъ) follows the story of Aleksandr Kolchak, played by Konstantin Khabensky.
From an article in the Washington Times:
To the Communists, he was an archvillain: a defender of the oppressors, a class enemy. And for decades, that's the way films and textbooks portrayed Adm. Kolchak, a leader of the fight to roll back the 1917 Russian Revolution, which gave birth to the Soviet Union. Now comes a $20 million state-supported movie epic that glorifies Kolchak as a failed savior of Russia. Such a reversal might seem odd, coming less than four years after Vladimir Putin was decrying the collapse of the Soviet Union as "the greatest geopolitical catastrophe of the century."
As it turns out, I've been reading a bit about about the North Russian Expedition sent by the West to aid Kolchak and like-minded figures. If you're bored, see J. F. N. Bradley’s Allied Intervention in Russia, John Sliverlight’s The Victor’s Dilemma, Robert Jackson’s At War with the Bolsheviks, Clifford Kinvig’s Churchill’s Crusade or Andrew Soutar's With Ironside in North Russia.
