Devastated and depressed by the death of his girlfriend Iris—brutally murdered by an unknown killer—Aristodemo purchases a life-sized sex doll named Persephone. He subsequently descends into a state of progressive delusion, eventually convincing himself that Persephone has come to life. As he spirals into increasingly extreme sexual acts with the doll, the killer who murdered Iris strikes again.
