Sally (Lulu Chu) is now happily living with her best friend Heather (September Reign). But before long, it turns out that sex with Heather isn't enough to sate the hungry thing inside Sally's body, and the temporary solution that Dr. Petit (Tommy Pistol) gave her is not working either. Sally becomes desperate and runs off.Dr. Petit manages to find Sally, along with the mysterious nun Dorothy (Ginger Lynn), but Sally is in a bad state. Dr. Petit transports Sally to his office, and he and Heather try to assist her. After the thing inside Sally taunts Dr. Petit and Heather, Sally pleads for help, telling Dr. Petit that she needs fresh semen and needs it NOW. Dr. Petit knows what he must do, but will it be enough to save Sally? Can ANYTHING save her?
