Welcome inside the world of junior show jumping, where America's top teenage riders and their trainers, horses and families engage in the daily drama of the high-powered horse circuit.

These teens are the best of the best — the Michelle Kwans of the riding world — and they're out to prove who's No. 1.

As the horses and riders compete for the Maclay National Championship, the biggest junior equestrian competition of the year, we explore what it takes to make it both in high school and the ring, the pressure and sacrifices of the riders' families, the athleticism and bravery of the horses, the dedication and ambition of the coaches, and above all, the emotional bond between horse and rider.

From farm girls to Park Avenue princesses and backyard ponies to $500,000 champion horses, follow the riders as they compete with each other and themselves for the ultimate junior title.
