Gold-mine operator "Boss" Kruger (Raymond Massey) has certainly earned his nickname. A frontier dictator, Kruger runs his mine like a prison colony. Most of his workers are, in fact, fugitives from justice and are given dubious "protection" by Kruger. Two of the laborers are Judith Burns (Ruth Roman) and Bob Peters (Dane Clark), both on the lam from the law. Judith and Bob befriend lawyer Aubrey Milburn (Robert Douglas), who seeks to prove that Kruger is a murderer.
