In 1943, with Lvov's 150,000 Jews having been exiled, killed, or forced into ghettos and facing extermination, a group of Polish Jews sought refuge in the city's sewer system. The last surviving member this group, Krystyna Chiger, provides a first-person account of those fourteen months with her family. Also describes Leopold Socha, a Polish Catholic and former thief, who risked his life to help Chiger's underground family survive, bringing them food and supplies. 2009, c2008.
