Overview: Reese and Erik attempt to deliver a mine payroll but are ambushed by the Sweet Gang, a hillbilly gang lead by Ma Sweet, and have to retreat. Parmalee, Chad and Joe ride to join them, meanwhile Erik tries to find another route to the mine but is taken prisoner by the Sweets, becoming a romantic interest for Billie Lou Sweet. The Rangers use the local sick wagon to transfer the mine payroll. They are attacked by the Sweets who, holding Erik as prisoner, force them to disarm and surrender the payroll. The Rangers use psychology and then force to capture them. Reese, Chad and Joe catch the measles due to being around or in the sick wagon.
