Bonnie and Sam are best friends. No one loves horses the way they do.
When Bonnie whispers to them, they understand, and Sam always knows if
they need a drink, or a hug, or a race around the paddock. Now it's time
for the Royal Show, and the girls are going to help their riding teacher
get ready for a big competition. But in a backyard near the showgrounds
they see a sad, starving pony--and it's Bonnie and Sam to the rescue!
