[1] On 1 September 1939, Germany invades Poland, after which a regulation was promulgated that all Polish Jews should move to the new Warsaw Ghetto.

The film tells the moral dilemmas faced by Adam Czerniaków, head of the Judenrat in the Warsaw Ghetto, who had to carry out orders of the German authorities, including sending Jews to the Treblinka extermination camp.

A group of Polish Jews decide to rebel against the Germans and not to lend a hand to the murder of their brethren.

The rudiments of resistance are planned by Mordechai Anielewicz together with Yitzhak Zuckerman who laid the foundation for the Jewish Combat Organization, Zydowska Organizacja Bojowa (ZOB).

The movie was filmed in multiple locations, including Bratislava, Slovakia and Innsbruck in Tyrol, Austria.
