In 1907, the Russian authorities learn that a revolutionary known as 'Granddad' is living in hiding with his brother. The revolutionary is soon arrested and sent to Siberia. After ten years of struggling to survive in harsh conditions, he is finally released when the Tsarist government is overthrown in February 1917. He is welcomed home as a hero, but he soon finds that even his own son has different views than he does about the future of Russia.
