Hopalong Cassidy: Santa Fe Marshal

Hopalong Cassidy, in the position of a U.S. Marshal, comes to town disguised as a medicine man in order to clean out a gang of thieves. After Hoppy sets up the medicine wagon in town, another wagon breaks loose and the horses run away with it. Hoppy manages to stop the wagon and endears himself to the owner, an elderly woman, "Ma" Burton who takes him in as a lodger. Hoppy soon discovers that Ma is head of the very gang he has come to investigate. Before he can round up the gang, one of them rides off with the medicine wagon, holding a girl hostage.
