Sociologist Nechama Tec explores the story of one woman, Stefa Dworek - a Polish Christian - and her motivation to shelter a Jewish woman during the Holocaust. If caught rescuing a Jew during this time, Stefa would have faced imprisonment or worse. Yet about 2 percent of the Polish Christian population chose to hide Jews in a nation known for its long history of antisemitism. Nechama Tec and scholar Ervin Staub conclude that the decision to rescue Jews had little to do with the rescuer's religion, nationality or schooling but was because such individuals refused to go along with the crowd and were accustomed to performing good deeds. Stefa Dworek was one such individual.
