An anthology of four nightmares: a man is tormented by love and a twisted creature in his apartment; two men confront each other in a damp, filthy basement; a withered man nurtures a growing creature; a man believes something is growing inside him; and finally, an old man is visited by a childhood friend that could be his darkest nightmare. The victim in each story is forced to confront a fear eating them from the inside out. Their choice? Deal with the fear or die with it.
