A musical retelling of the centuries-old story of the Pied Piper.

A minister seeking re-election promises the people he will rid their country of its rats, even though he knows they do no harm. A stranger, who has no face, offers to lead the rats away in exchange for money. A bargain is struck and the rats disappear, but when the minister is re-elected he reneges on the deal, saying the money has been better spent on "barbed wire and education", and the stranger leads the children away to the light "inside the little hill".
