June 1941. Hitler's armies race toward vulnerable Leningrad. In a matter of weeks, the Nazis surround the city, cut off the food supply, and launch a vicious bombardment. Widowed violinist Sofya Karavayeva and her teenage granddaughter, Yelena, are cornered in the crumbling city. On Leningrad's outskirts, Admiral Vasili Antonov defends his homeland and fights for a future with Sofya. Meanwhile, Yelena's soldier fiance transports food across the Ice Road--part of the desperate effort to save Leningrad. With their help, the two women inch toward survival, but the war still exacts a steep personal price, even as Sofya's reckoning with a family secret threatens to finish what Hitler started.
