Ian Telford is a 34 year old secondary school teacher who does not drink or smoke, disapproves of blood sports and knows very few people, if any, who went to private school. But that's all about to change. His little sister is marrying a Hedge Fund Manager, Angus "Johnners" Johnson. Not content with the standard "pub crawl, curry, lap dance" format, best man "Ledge" has gone the extra mile organising a stag hunting adventure in the remote Scottish Highlands for Johnners and his chums. On the itinerary: plenty of plonk and a rare opportunity to murder the most beautiful animal in Europe. But our hunters are about to become the hunted. Out there, lurking in the trees, is a killer of a completely different kind. Whoever or whatever it is, is hell bent on making this Stag Do messier than they ever imagined.
