Orphan Tom has been sent to live in the Scottish Borders with an uncle and aunt he's never met.
But a remote sheep farm in Scotland is a different world from his home in London. Tom is lonely and struggles to fit in with strange new people and their odd ways, until his uncle gives him a sheep dog puppy called Flash.
Flash is loving, clever and brave and Tom is determined to make him the best sheepdog he can be -- perhaps even a champion! But when the day of the competition arrives Tom faces a difficult decision -- will he leave his new life, and Flash, behind?
