The Vow

In 1924, veteran Bolshevik Petrov, a resident of Tsaritsyn, carries a letter to Vladimir Lenin, to inform him of the Kulak brigands that roam the land, spreading death and misery. The Kulaks murder him. His widow, Varvara, continues his quest, joining a group that travels to Moscow. When they arrive, they discover that Lenin is dead. In the Kremlin, Vyacheslav Molotov tells Anastas Mikoyan that now, Grigory Zinoviev, Lev Kamenev and Nikolai Bukharin will attempt to subvert the party by attacking Stalin, Lenin's devout disciple. Stalin, mourning his teacher's passing away, carries a eulogy in the funeral, calling for all attendants and all the people of the Soviet Union to vow to maintain his legacy. The people swear. Varvara sees Stalin and hands him over the blood-stained letter entitled "To Lenin". Varvara's son, Sergei, becomes an inventor, developing the first Soviet tractor with Stalin's encouragement. Her other son, Alexander, becomes manager of the Stalingrad Tractor Factory. ..
