Overview: During the Nazi occupation of eastern Poland, a small group of Jews in the city of Lvov tried to save themselves from the death camps by hiding in the sewers beneath the city for more than 14 months. Timewatch reunited four remaining survivors in 1988 to record their accounts. The oldest, Mundek Margulies, journeyed back to Lvov (now part of the Soviet Union) and with co-operation from local authorities, went down into the sewers and through the maze of tunnels to help describe this extraordinary episode of human courage and endurance from the Jewish Holocaust.
