Centuries ago, Baron Wolfgang MacLaren vanquished the Vampire Queen Carmilla in the remote Cragwich; however, before decapitating the evil vampire, she curses the locals and descendants of the baron, swearing that every woman would turn into a lesbian vampire on her 18th birthday. In the present day, clumsy, naive cuckold Jimmy is dumped again by his girlfriend Judy and misses her. His best friend Fletch is fired in his job of clown after hitting an annoying boy. The two broken friends decide to camp in the countryside to forget their problems, and Jimmy throws a dart at a map in a pub to decide where they should go. They head to Cragwich, and when they arrive in the Baron's Rest bar, they see four hot girls leaving the place in a Kombi. The innkeeper offers the guys the old Mircalla cottage in the woods, the same place the girls will lodge. Meanwhile, Lotte, Heide, Anke, and Trudi have trouble with their van, and when Jimmy and Fletch reach them in the forest, the girls offer the guys a ride to their cottage. They introduce themselves as students of folklore who they are researching the Vampire Queen Carmilla. When Fletch believes that he will have a night of beer and sex with three sexy girls and Jimmy and Lotte have a crush on each other, the cottage is surrounded by a group of lesbian vampires that vampires intend to use Jimmy and Lotte's blood to bring Carmilla back to life. They are abducted by the vampires, but Fletch escapes and meets Reverend Vicar, who tells him that Jimmy is a descendant of the baron and the only hope to stop the evil curse of Cragwich.
