CART DRIVER: Bring out your dead!
   We follow the cart through a wretched, impoverished plague-ridden village.
   A few starved mongrels run about in the mud scavenging.  In the open
   doorway of one house perhaps we jug glimpse a pair of legs dangling from
   the ceiling.  In another doorway an OLD WOMAN is beating a cat against a
   wall rather like one does with a mat.  The cart passes round a dead donkey
   or cow in the mud.  And a MAN tied to a cart is being hammered to death by
   four NUNS with huge mallets.
