After they save a zookeeper (Bernard Bresslaw) who is about to throw himself off a bridge. All because the newly built monster house has no monster to exhibit.
So the Goodies set off to Scotland to catch the Loch Ness Monster. They know they might be in for a long wait.
In the meantime they fight off the Scottish bagpipe spider. One bite and they do the Highland fling until they collapse.
In the meantime they find themselves fleeced by the Tourism agent (Stanley Baxter) who sells them all the provisions to bag a monster.
All the indications that the Loch Ness Monster is just another monster money making scam.
Enlivened by a sterling performance from Stanley Baxter. This contains all the Scots stereotypes and monster jokes. Even a quick glimpse of Andy Stewart, who usually was never allowed out unless it was Hogmanay.
