 Rocky Lane (Allan Lane) hits the trail when he gets word that one of two brothers in a partner-ship mining project has been killed by outlaws trying to gain possession of the mine. The other brother, Nugget Clark (Eddy Waller), a testy old sourdough, wants no part of the law, and is particularly set against the young sheriff, Keith Ames (William Henry), courting his niece Trudy (Gail Davis). Playing to the old man s ego, Rocky takes charge of the situation.
