The whole kingdom is plagued by the screeching, howling din made by the Nasties, so the King sends Sir Ned to deal with them.

A wolf, a witch and a troll help Ned along the way, but it turns out he has walked into danger - these three are the notorious Nasties themselves!

Luckily he works out why they sound so awful and teaches them to listen to each other, so they ask him to join the band rather than turning him into dinner.
