God's Crucible

While their father, Michael Kalmar, remains in a Siberian prison, political refugees Ivan and Irma Kalmar seek freedom in Winnipeg, Canada. However, they continue to encounter persecution at the hands of prejudiced neighbors, and from their father's enemy, Makaroff. Ivan's violin playing attracts the interest of Marjorie Menzies, but also the enmity of District Attorney Mortimer Staunton, a rival for her affection. During a party at Makaroff's home, Irma is insulted, and when her abuser is slain, Ivan is arrested. Michael, who has arrived in Winnipeg after escaping from prison, confesses to the murder. Ivan becomes a foreman in a coal mine, which Makaroff hopes to acquire illegally. After his plan fails, Makaroff attempts to blow up the mine along with its employees, but kills himself instead. Michael is freed by a family servant who admits to the murder, and Ivan becomes engaged to Marjorie.
