The story of three young men during the siege who were looking for an apartment that had survived the bombing, but found each other for life. Marat and Lika (she loved the proud Marat, but married Leonidik, who had lost his arm at the front) fled from their own happiness and are now painfully returning to it, learning to be happy again with such difficulty, as if learning to walk again. And Leonidik, for whom the burden of his love has become unbearable, unbearable, is learning to be free again with the same difficulty.
