Adam and his Shetland pony Haki have been inseparable.

Haki is clever and brave and Adam soon trains him to do things other Shetland ponies can't - to act, to dance and to follow the sound of Adam's bagpipes.

But Adam must move off the island to find work and selling Haki is the only way he can leave.

Then the pair performs at the Highland Show and a ringmaster is so impressed by the talented pony that he lets Haki, and Adam, join his travelling circus.

Haki - with Sondra the friendly elephant - become stars of the big tent but some of the circus folk are jealous of their success.

Can Adam protect his friend?
