In a German village in 1942, farmer Heinrich Marten is conscripted, leaving behind his wife Kathrin and sister Frieda. As the two young women cannot manage the farm alone, they are given help by the state: a prisoner of war. The Russian Alexei is emaciated and has to be nursed back to health by the women. Working together in the fields and on the farm, Kathrin and Frieda inevitably get closer to the Russian. The resolute Frieda is courted by the local farmer Otto Lange and is at the same time dependent on him. A love affair develops between Kathrin and Alexei. They make love in a shed. But the couple is discovered by a soldier and Alexej flees. He is caught by young Nazis and taken away.
