Tigers and T-34s lock horns in this dramatization of the 1943 battle for Kursk, in southwestern Russia, the greatest tank battle in the history of armored warfare. The Berkos are a family divided by politics: Dimitri Berko, the patriarch, is an old-school Cossack driving a T-34 under the command of his estranged son, Valentin, a fervent Communist; daughter Katya is a Night Witch bomber pilot.
