Guinea Pig 4: Devil Woman Doctor (1986)

Guinea Pig 4: Devil Woman Doctor (1986) A mad doctor displays a selection of her more gruesome case studies. Starting with one family whose heads explode if they get angry and a woman whose heart explodes if she's surprised, the doctor then presents us with a man whose right half wants to kill his left. Other subjects put on display are the effects of going to a sauna if you're a man who sweats blood, the possibilities of romance between woman and zombie, and a game of one- upmanship between hospital patients.
