The TARDIS lands the Doctor and Martha in the Lake District in 1909, where a small village has been terrorised by a giant, scaly monster. The search is on for the elusive 'Beast of Westmorland', and explorers, naturalists and hunters from across the country are descending on the fells. King Edward VII himself is on his way to join the search, with a knighthood for whoever finds the Beast.
