The residents of the village of Staroje Dudino, located four kilometers west of the Soviet border, are completely dependent on the wealthy Novik, whose interests are protected by the local police and clergy. Novik is actively stirring up ethnic strife between the Jewish poor and Polish workers. During the traditional "black crown" ceremony (a wedding ceremony for an old man and an old woman), a group of factory workers led by the communist Haidul, together with the Jewish poor, attack the police and free Boris Bernstein, who had been sentenced to death.
