Theatrical Release Information:
Il Plenilunio delle vergini

Low budget blood and breasts abound in this Italian exploitation horror film that offers yet another variation on the grisly but true story of a 17th-century Hungarian countess, Elizabeth Bathory, who bathed in the blood of over 600 virgins to retain her youthful appearance. This time the trouble begins when a pair of twin archaeologists begin searching for the mythical Nibelungen Ring, which is said to possess magical powers. Unfortunately, the ring rests upon the finger of a devilish Transylvanian countess who loves a good hot blood bath. One of the brothers heads for her castle. When he does not return, the other brother follows and discovers that she has turned the first brother into a fearsome vampire. ~ Sandra Brennan, All Movie Guide
