Jakub Szapiro, Jewish Boxer and Enforcer
In 1937 Warsaw, Jakub Szapiro, a celebrated Jewish heavyweight boxer, works as the chief enforcer for Jan 'Kum' Kaplica, a socialist-connected crime boss who runs protection, debt collection and street muscle. Szapiro's violence enters the life of the boy Mojżesz Bernsztajn through his family's ruin, yet the boy attaches himself to Szapiro as an errand runner and worshipper. As nationalist groups beat Jews in the streets and Kaplica's power weakens, Szapiro fights both for the underworld succession and against the rising fascists.
