Two college girls travel through the French countryside trying to locate the tomb of a legendary vampire/witch. Unfortunately for them, they find it in an old castle owned by a count who has his own dark secret – which the title of the movie pretty much gives away. When they accidentally wake up the vampire, well, as the posters put it: “Things happen that have never been seen by human beings. The blood flows like vintage wine!”
Star Paul Naschy also co-wrote the screenplay, under the name Jacinto Molina.
