Captive of the Midnight Vixens

Hiking into the mountains of Transylvania, Roy Travis stumbles on Valeska, a
young woman suffering a sprained ankle. Helping her back home to a huge,
forbidding mansion, he waits for a storm to pass. He dines with Valeska, her
twelve very odd sisters, and Karel, the estate manager. Joining Karel for an
after dinner drink, he drifts into a drugged sleep and later awakens bound to
a bed, being sexually teased by one of the sisters. When he reports the
incident, he's told he must be dreaming. But the strange goingson continue. He
sees the sweet maid Rozalia abused by Mara, a sadistic housekeeper, then
accompanies Karel as he hunts the woods for wolves, using a rifle with silver
bullets. Soon afraid for his life, he tries to leave, but is stopped by Karel
and Mara, who take him to the basement where he's stripped and locked in a
cell. He learns then that Valeska and her sisters keep many men prisoner
there, to service them sexually and satisfy their vampire appetites. He, too,
will succumb to the will of these beauties at a cruel banquet where the
sisters will torture him and drink his blood. As the abuse becomes more cruel,
he learns that even Karel is subject to these wicked femmes. Thrown together
in their misery, Roy falls in love with the maid Rozalia and they dream of
escaping. But is there any hope for these hapless lovers, or the other
imprisoned victims of this nightmare?
