Military doctor Kwiatkowski, serving in a barracks hospital on the Western Territories, is rewarded with a week's leave after successfully operating on Colonel Kiziora of the UB. He and his friend steal a truck bound for Warsaw, where among the ruins of his former home he meets his prewar neighbor Krysia, instantly falls in love, and, after a brawl with a Russian officer at a dance in the surviving "Polonia" hotel, pretends to be a high-ranking UB colonel to save face.
