Witek and Krysia, a married couple, move to Warsaw and have nowhere to stay. They rent a room in a house with many other lodgers. Witek dreams of their own house and draws a sketch of their future home, marking the place where his wife will sleep with the word "treasure". The other lodgers find the draft and a frantic search for the treasure begins.
