A group of tourists arrive to see the botanical gardens on a small island off the coast of Spain. The only inhabitants of the island are the famous botanist Baron von Weser and his two faithful servants. All of the other residents fled after a series of mysterious deaths. When the car driven by the tourists' guide hits one of the baron's servants, von Weser explains that the death was due to a rare and incurable disease, not the accident. That night, the guide and Cora Robinson, one of the guests, are found murdered with all the blood drained from their bodies. Is there a serial killer at large, or is it something even more dangerous? Released here on video, uncut and in it's original aspect ratio for the first time, this highly enjoyable and pioneering Spanish-set horror is packed with entertaining and surprising twists and turns. Something of a lost classic, the film plays like a twisted version of an Agatha Christie story, but with gallons of gore. The movie was written and directed by actor Mel Welles, who created the role of Gravis Mushnik, in the original version of THE LITTLE SHOP OF HORRORS. In the role of Baron Von Weser, and gleefully chewing up the scenery in one of his most delirious performances, is actor Cameron Mitchell.
