A scientist finds himself walking a fine line between reason and fantasy in this family-oriented drama. Dr. Jonathan Dempsey (Ted Danson) is an American scientist who has devoted his career to searching out the truth behind contemporary legends and psudeo-scientific phenomena like Bigfoot, which has not gained him much credibility among his peers. Dempsey's superior, Dr. Mercer (Harris Yulin), has a new project that would seem to be right up his alley -- Mercer wants Dempsey to travel to Scotland to prove once and for all that there is no such thing as the Loch Ness Monster. Dempsey takes the assignment and settles into a small hotel near the Loch run by Laura MacFeteridge (Joely Richardson), a single mother with a young daughter, Isabel (Kirsty Graham). Isabel strikes up an immediate friendship with Dempsey while her mother soon takes a more mature interest in the American scientist, but most of the locals don't take kindly to the notion of an outsider flying in to prove that Nessie isn't real, especially the town's self-proclaimed monster expert the Water Bailiff (Ian Holm). What Dempsey does learn about Nessie surprises him a great deal -- and so does his decision about what to do with his findings. Jim Henson's Creature Shop pitched in for the special effects sequences with Nessie. Loch Ness was released theatrically in Europe, but had its American premiere as a network television presentation.
