Beneath the Flesh is an anthology of four nightmares. In Id, a man is tormented by love and a twisted creature in his apartment. In The Basement, two men confront each other in a damp, filthy basement. In The Child, a withered man nurtures a growing creature. In The Insides, a man believes something is growing inside him. Finally, in Boxhead, 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 that is eating them from the inside out. Their choice? Deal with the fear or die with it.
