Jim Harkness has made every sacrifice to give his younger brother, Dick, an education and welcomes him home from college. Dick, however, did not go to college but became a member of the notorious Black Hat Gang, which has been ravaging the countryside. Jim prevents a train robbery by the gang and captures one of the masked bandits, who turns out to be Dick. He returns the goods his brother stole, Dick repents, and Jim marries May Lacy, the sheriff's "school m'arm" daughter.
