Wandering Jews from other lands, weary and sick from torture and oppression, land in Poland during the 14th Century. These unfortunate people appeal to King Casimir for help and sympathy. They plead for deliverance from their past continued inquisition. The count learns of the arrival of the Jews, and with his accomplices, they endeavor to persuade the king from allowing the Jews to remain in Poland, when the good priest Prandola intervenes, and manages to persuade King Casimir to allow the wanderers to remain and make their home in Poland. The Jews pray and thank the king for befriending them. The count is enraged to think that his persuasion was of no avail. He secretly plots to incite an uprising against the Jews. In the meantime the king meets a young Jewess, named Esther, the daughter of a rabbi. The king tells the count of his love, and when the villain spies Esther he himself falls in love with her. A few days later, the count steals the young Jewess from her home, and places her in the care of an old drunken hag. He then reports to the king that the young Jewess has been drowned by her infuriated father, to which he adds that for a just punishment the Jews deserve execution. King Casimir sends out an edict to kill all the Jews. The night before the terrible massacre, the count and his nobleman feast and get drunk. He orders the spies to bring Esther that evening to him and to tell her of his revenge against the foes. As the spies try to drag the poor girl out of the room, one of the men steal a bottle from the old hag. This causes a brawl, and in the fight that ensues, the old woman is struck on the head. The men carry the Jewess away. The old woman rises and confronts the priest. The old hag confesses to him the entire incident. He sees the king and reports to him the story, and tells him that the Jewess is in the power of the count. The king hurriedly rushes to the palace of the nobleman and in a disguise rescues the girl from the hands of the count. King Casimir orders the arrest of the count and immediately sends a courier to the scene of the execution, who arrives in time to save the Jews from the awful sacrifice. The king tenders a banquet in honor of his marriage to Esther, "Henceforth, there shall be peace between Poland and the Jews."
