At Loch Ness, Scotland, scientist Dr. Abernathy is killed by slipping off some rocks, after seeing something in the loch and taking a single photograph of it. Months later, American zoologist and freshman college tutor, Dr. John Dempsey, is asked to replace Abernathy and dispel the myth of the Loch Ness Monster. Dempsey is reluctant to do so, having ruined his career by trying to prove the existence of the Sasquatch. He agrees to go for the money, which would allow him to pay alimony to his ex-wife, naming a newly discovered species of wasp after her.
