The Doc (Martin Clunes) is in need of a bit of distance from the small village of Port Issac, so when the local real estate agent shows him the ramshackle, middle-of-nowhere property Tregrunnt Farm, it's love at first sight. Problem is the Bowden family from London also have their eye on the property for holiday cottages. After being hoodwinked in the deal and increasingly desperate to buy the property, Doc decides to try and spook the family into leaving with the help of the legendary Beast of Bodmin. He returns to prowl around Tregrunnt with an absurd beast printmaking device, but the exercise is doomed and Doc decides to change tactics. Rather skeptically, he resorts to an old Cornish witch's trick — a cloutie; a small ribbon of cloth which, if attached to a tree and wished upon, will make wishes come true. But the caster of the spell must beware — what you wish for will come back at you threefold.
