After a luckless prospecting trip, Billy starts homeward across the desert, mounted on his little burro with his pick, shovel and pack strapped up behind him. Finally he comes in sight of Red Dog Gulch and, hungry and thirsty, he pushes on toward the city. Susie is the daughter of the town drunkard. She starts out on her horse for a little ride, and a little way from town is attacked by Pedro and Little Casino, two Mexicans, who try to steal her horse. Billy happens along, runs the Mexicans off and takes Susie back to town.
