As World War II comes to an end, mid-40s Lena Brucker finds herself alone. Her children have left home and her husband has been stationed on the eastern front for years. Just when life appears to have become stagnant, Lena is given an unexpected new lease on life. After an evening at the cinema, she ends up taking Petty Officer Bremer home with her. She cooks for the young man, who reminds her of her son, and shares a drink with him. A pleasant visit turns out to be more than just friendly. Lena even offers Bremer a place to stay, at first only for the night, but then for the long term. Facing the cold, hopeless front as an alternative, Bremer decides to desert in the morning. A love affair unfolds, with the war just outside the door. But the greater threat to Lena's new life is the impending peace. Eventually, she decides to hide news of Germany's surrender from Bremer and tries to keep him a prisoner in her manufactured war game.
