A fat middle-aged man in German officer's uniform gets off a train somewhere in Russia in winter. He is a doctor who has just been called up we learn eventually. This is the end of the line- the Germans are about to retreat. He goes to a hospital which is being evacuated and is thrown out. Kicked out he wanders with another conscript- a failed actor turned postman. The postman is deafened by a shell explosion. They meet their Russian equivalents, others as bad at killing as they are, while other Russians and Germans kill one another around them.

Kashtanov, professor of medicine and famous Moscow surgeon, is experiencing midlife crisis. Suddenly he decides to leave everything and escape to the countryside in order to spend some time with old friends.
