The girls of The Saddle Clun have headed West to the Bar None Ranch. This time they've brought their friend Emily, who has cerebral palsy. Emily is going to help the ranch's owner make it accessible to riders with special needs. Then the four girls meet a guest their own age. She's a former rider who has lost part of one leg in a motorbike accident. She doesn't plan to get on a horse ever again. In the meantime, The Saddle Club and Emily are riding so much, they're saddle sore!
