Acclaimed director and certified lunatic Jim Powers returns to the Land of Dementia. Once again, an innocent girl is cast into a bizarre world of fetish and anal sex. Dementia #4 is so perverse and so twisted that mere words can't begin to describe it. With a star-studded cast of cock-crazy madwomen and the freakiest sex imaginable, you're going to think you're suffering from a Dementia of your own.
