In April 1942, Hitler and Mussolini plan the huge offensive on the Eastern Front that will culminate in the greatest battle in human history. Hundreds of miles away, Pyotr Vavilov receives his call-up papers and spends a final night with his wife and children in the hut that is his home. As war approaches, the Shaposhnikov family gathers for a meal: despite her age, Alexandra will soon become a refugee; Tolya will enlist in the reserves; Vera, a nurse, will fall in love with a wounded pilot; and Viktor Shtrum will receive a letter from his doomed mother which will haunt him forever. The war will consume the lives of a huge cast of characters - lives which express Grossman's grand themes of the nation and the individual, nature's beauty and war's cruelty, love and separation.
