A Holocaust survivor (Teresa Marczewska) confronts an ethics professor (Maria Kościałkowska) who once refused to help her on the basis of this commandment.

Zofia (Maria Koscialkowska) is an elderly but sporty university professor who is friends with stamp-collecting neighbour Czesław "Root" Janicki.

Janicki, the neighbour, enters and proudly shows Zofia his series of 1931 German stamps that he has recently acquired.

Elżbieta asks to be taken to the family that had offered to help her, but when she gets there, the man, a tailor, refuses to speak about the war.

The story was based on an experience of the filmmakers' mutual friend, the journalist Hanna Krall.
