Newspaperman Ben Jarrett, crusading for the eradication of gambler Henry Judd and his henchmen, who he holds responsible for the crime wave in the community of Sundance, is beaten up and about to be run out of town when Cisco and Pancho arrive to help. Learning of the situation from Jarrett and his sister, Cisco and Pancho set to work housecleaning. They are almost killed, however, when Judd substitutes one of his men for a Federal Marshal that Jarrett had sent for, but, in the end, Judd and his men are hauled off to prison.
