Plot.
John and Kathleen Strauss are a couple attempting to uncover the secret to John's rare blood disease. They encounter Dr. Marlowe, who is intrigued by the case. They are unaware that the island which they are about to set foot upon is home to the Van Dam family, mutant-like creatures who have become deformed and bloodthirsty from centuries of inbreeding. Their mutation began with their relative Eva Van Dam, who had a twincest relationship with her twin brother. Also, they are fully functioning hermaphrodites, capable of reproducing with themselves. They need to survive on (dead or alive) human flesh.
John discovers that he is a Van Dam, born normal looking and taking part in normal society, but his rare blood disease can only be suppressed with human flesh and sex with his siblings.
Reception.
Critical reception was predominantly negative. HorrorNews.net panned the film overall, criticizing it for its "abundance of clichés" and commenting that they'd "be damned if there was anything in this picture worth seeing again". "Moria" gave the film two stars and stated that "one can see that a number of sequences have been designed on paper in a way that could have had some shock impact had they been directed by someone with half an ounce of talent".
