Tilly Redbrow doesn't just love horses - she lives, breathes and dreams them too! Tilly is elated that she and her beloved horse, Magic Spirit, have been selected to train for the British Equestrian Junior Squad. It's like a dream come true. She is looking forward to spending a week at top event rider, Livvy James' yard and being taught by a professional. Together with her team mates Anna, Ben and Kya, they start their days early and finish late working in the yard, getting to grips with stable management and riding with Livvy. It's not easy, there's a lot to learn and the strain begins to show with jealousy and rivalries that threaten to break the team as they all try to earn a place in the limelight.
