Max is a young boy living in an ordinary tower block. He longs for adventure in his life - then one day - DOOF! - a flying pony called Kevin crashes into his flat, blown in by a magical storm!

The storm causes a huge flood, and soon Max's town is submerged in water. Luckily for the town, Max has a flying pony to come to the rescue, and luckily for Kevin, he has a new best friend and a constant supply of his favourite thing - biscuits.

Together Max and Kevin will embark on many wild adventures together.
