TV John's long-lost brother, the one-eyed, one-legged, one-armed Kenneth McIver, is Sprung from a South American gaol by millionaire Torquil Farquar McFarquar. Ex-patriate McFarquar has a passion for all things Scottish and has heard that Kenneth knows the whereabouts of the real Stone of Destiny, coronation stone of the ancient Scottish kings. Scenting a fortune in the offing, Kenneth sets off for Lochdubh, accompanied by mysterious hypnotist Ava Grimm. Meanwhile, TV John has had premonitions of the impending death of someone very close. How can the villagers convince him it's all in tile mind?
