In the second of this series of "Streamliner" westerns from Hal Roach (preceded by "Dudes Are Pretty People" and followed by "Prairie Chickens"), wandering cowboys Pidge Crosby (Noah Beery Jr.) and Jimmy (Jimmy Rogers) take a job breaking horses for Tom Pendergrast (William Henry) at the railroad corral, and the horses stampede through town when Pidge,preoccupied as usual with chasing a girl, leaves the door open on the opposite side of the railroad car Jimmy is driving the horses into. When Pidge learns that the girl, Doris Lane (Mary Brian), he is chasing has a do-gooder heart and is fond of coddling prisoners in the jail ran by her uncle, Sheriff George Lane (William B. Davidson), he gets himself thrown into jail. The plan is working good until big-city gangster Sluggsy Baker (Marc Lawrence) is also jailed, and sends for his moll Gert (Iris Adrian), who he calls "Ma", to bring his henchmen and break him out. They also take along the unwilling Pidge.
