The Pied Piper eschews the romanticism of Robert Browning’s poem and returns to the grim Grimm Brothers source. Pop singer Donovan plays the 14th century piper hired by a duplicitous burgomaster (Donald Pleasence) to rid the town of Hamelin of its rats. The piper does what he’s asked, but is denied the payment promised him, in revenge, he leads all of Hamelin’s children out of town, never to be seen again.
