Ballyyahoo is a tiny, magical town in Ireland. Christmas in Ballyyahoo was going to be the best one ever until Santa and Rudolph showed up on Christmas Eve. Santa and Rudolph are not what they seem, they're a pair of evil crooks. Those villains have no intention of wishing anyone a happy Christmas, especially not anyone from Ballyyahoo and they steal all the presents away. Kevin and Gerry try their best to save Christmas and the boys set off on their bikes, desperately seeking Santa, but when they get lost in the woods, near the terrible town of Ballyuseless, Kevin and Gerry begin to wish they'd stayed at home. Soon, they find themselves trapped on a boat, in the middle of the stormy Irish Sea, there's only one person who can help them and that's the wonderful Witch of Ballyyahoo.
