''In Darkness'' is a dramatization of a rescue of Jewish refugees during World War II in the German-occupied city Lwów (Lemberg in German, L'viv in Ukrainian). For over a year, a Polish Catholic sewer maintenance worker and burglar, Leopold Socha along with his friend and co-worker Szczepek Wróblewski, hid and cared for a group of Polish Jews who had escaped the massacres and deportations during the liquidation of the Lwów Ghetto. At first the men demand daily payment for their help but they continue to aid the group long after the Jews' money has run out and aiding them had become ever more dangerous. The Jewish ghetto had been established in 1941 and the Nazis decided to liquidate it in June 1943. The Soviets took over Lwów city in July 1944, by which point Socha's band made up 10 of the fewer than 1,000 surviving Jews in the city. Socha's and Wróblewski's actions and those of their wives led to their recognition as Righteous Among the Nations recipients.
