Two boarding schools sit on either side of a lake. At times they are against each other, at times they work together. That's the way it's always been with the boys from Shiverstone Castle and the girls from Rose Cliffs.
The Shiverstone Knights think things are much too quiet at the castle, until the new kid arrives with a racing bike, just in time! Every part of Andy - heart and lungs - has to be tested out. Is he a bragger and a fraud or isn't he? Then Andy turns up with a steam engine and a super-prank, which leads to a hugely humorous debut on a TV show. Finally the Knights know the truth . . .
