Basia and Stefan are a young married couple during World War II who risk their lives to bring aid to Jews. He is an architect, she a nurse--a member of "Zegota" (the Polish underground organization to aid Jews in occupied Poland which operated under the auspices of the Polish government in exile). The series takes place both during the war and in the present day. Basia and Stefan meet accidentally, fall in love, and marry. Basia is active with the underground from the beginning of the war; Stefan is not, but a family tragedy changes his attitude.—Anonymous
