With Ty in the hospital, Amy is struggling to keep up with the Heartland chores and stay positive. But when she agrees to help train a wild Mustang, Amy starts to doubt everything - including herself.A new horse has arrived at Heartland. It is a stunning blue roan stallion - a Mustang that was purchased at a round-up out West. He has a beautiful, independent spirit. Amy understands how to work with strong-willed horses. She has always had a sense of how to approach each one. With time, even the most defensive and fierce horses have grown to understand her, to yearn to reach out to her and make the bond. But this horse is different. He isn't angry or misunderstood. He is proud. When Amy watches him gaze out over the paddock fence, she wonders if he was meant to be wild and free.
