In a German infantry unit retreating from Russia in the spring of 1944, Ernst Graeber's conscience is revolted by the execution of captured civilians. Given his first furlough for over two years, he returns to find his family home bombed and his parents gone. Calling at the house of the family doctor for information, the daughter Elizabeth tells him her father is in a concentration camp because of an unwise remark. Allied bombing continues by day and by night.

An old school friend who is now the local head of the Nazi Party offers Ernst accommodation, food, drink, and women. But he prefers to stay with fellow soldiers billeted in a hospital and to get closer to Elizabeth. The two go to the one restaurant still open, which is destroyed that night by bombs.

Each alone in the world, they agree to an immediate marriage, but Elizabeth's family home is flattened by bombs and they take refuge in a ruined church. Elizabeth gets a summon to Gestapo headquarters, which Ernst intercepts and attends as her husband. He is given her father's ashes, which he secretly buries in the churchyard. Visiting his former teacher, who helps Jews on the run, he is told there is no excuse for the German military's crimes against Russians and of the German state against its own citizens. Ernst and Elizabeth find lodgings for the rest of his leave.

Returning to the front, he finds a fellow soldier who is an ardent Nazi about to shoot captured civilians. As the two are alone, he kills the other soldier and tells the civilians to flee. One of them picks up the dead man's rifle and shoots Ernst dead. He had not finished reading a letter from Elizabeth, saying that she was expecting their child.
