A patient, Tommy (Tommy Pistol), is heading into a routine surgery. He's a bit nervous, but the nurse (Anna Claire Clouds) assures him that everything will be fine. However, just before the procedure begins, the nurse and the surgeon (Ashley Lane) start acting a bit suspiciously.
When Tommy becomes fully alert after the surgery, he finds himself in the same room, but now he's all alone… and something feels very, very wrong. He frantically removes his bandages, and is horrified to see that his penis is completely gone. Tommy panics, but he finds a note telling him to go to the basement.
Tommy enters the basement, and is shocked to find that the surgeon has transformed into a terrifying monster, and she's using Tommy's detached penis to fuck the nurse. Tommy pleads for his cock back, but the monster says it will cost him his soul and much more, because she wants to create a human-demon hybrid. Tommy is desperate, so he agrees to the bargain. Tommy's dick is reattached to his body, but now he has to fulfill his half of the deal by having a threesome with the monster and the nurse until their twisted desires are satisfied…
