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.
