Izzy Beaver helps to rescue Daisy the cow when she happens to fall into a ditch.
Farmer Jones is very pleased with Izzy for saving his cow so he treats him to a trip, with him in his wagon to Wales as he needs to pick up some slates at a slate quarry.
Izzy has a great time exploring a copper mine and playing on the swings and slides in Wales. He even goes up in a hot air balloon.
However things go wrong for Izzy Beaver when he loses Farmer Jones. The farmer has gone back home without him so who will come to his rescue this time.
