Plot

The Mystery, Inc. gang travel to Loch Ness to see Blake Castle, home of Daphne Blake's Scottish ancestors and her cousin, Shannon Blake, for the upcoming annual Highland games. Upon their arrival, Shannon informs them that the castle has recently been terrorized by the Loch Ness Monster. Along the way, the gang encounter Del Chillman, a Loch Ness Monster enthusiast and amateur cryptozoologist; Professor Fiona Pembrooke, a scientist who has staked her scientific career on proving the monster's existence; local competitors and brothers Colin and Angus Haggart; their father Lachlan; and Sir Ian Locksley, the games' head judge, a rival of Pembrooke's, and director of Scotland's natural history museum who firmly believes the monster does not exist.
