Ollie, head wrangler for the Triple R Ranch, herds the riding stock from the range into the corral where the boys arriving for summer camp can see them. Spin, a highly competent camper from last summer, jumps from the fence onto the bare back of his horse from last year, Sailor. Bill Burnett, the camp counselor, reprimands him. Freddy is a glasses-wearing tenderfoot whose parents are very protective. Speck has a penchant for pets of all sorts. Last to arrive is Martin Markham, the spoiled grandson of a rich grandmother who has raised him after his parents died. He has even brought his butler Perkins who will stay at the camp with him helping out in the kitchen.
