In this pilot episode, Danger Mouse and Penfold are dispatched to Loch Ness to investigate the theft of bagpipes and increased activity of the Loch Ness Monster. They uncover a plot by Baron Greenteeth (known in later episodes as Baron Greenback) to find "The Lost Chord," a musical note capable of causing great destruction.
