A Russian family, the Turkeltaubs, emigrates to the US before the Communist revolution that overthrew the Czar. One of their twin sons, Schulke, disappears and is believed dead before they leave. After they settle into their new country, the family does well: the surviving twin, Nicholai, becomes a crusading District Attorney. One of the cases he is assigned to prosecute is that of small-time gangster Jacob Talinef, who has killed a former girlfriend of Nicholai's. Further investigation of the case, though, reveals a shocking secret.
