A heavy summer storm brings a touring horse circus to Kaltenbach, the stud farm where Ari now calls home. Ari finds friendship in the circus boy Carlo and gets introduced to the fascinating world of trick riding. Soon Ari notices that the show horse Hurricane, aging and injured, is still being forced to perform by the cruel circus director Yiri. Ari and Carlo enlist Ari’s faithful black stallion Windstorm in a plan to save Hurricane, but Yiri has other plans which will endanger Windstorm. It will require some last minute help from Mika to save both magnificent creatures.
