Danica, Beatrix, Melody, and Sarah all arrive to Merrick Academy for the start of freshman year. The prestigious boarding school focuses on equestrian sports, attracting students from all over the country. Danica plans on using her time at the school to train for the Olympics. Beatrix switches her cowgirl boots for tall boots, as she has a desire to master jumping. Melody focuses on dressage while problems from her past catch up to her. And Sarah has never ridden a horse before arriving at the school. These roommates may be drastically different, but they band together to take on a daunting task: surviving the team tryouts.
