Two beautiful women, Fran (Marianne Morris) and Miriam (Anulka Dziubinska) roam the English countryside. They lure unsuspecting men to their estate for orgies of sex and blood. But when an innocent young couple John and Harriett (Brian Deacon and Sally Faulkner) stumble into the vampires' lair, they find themselves sucked into an unforgettable vortex of savage lust and forbidden desires.

Effective use is made of erstwhile Hammer horror set Oakley Court. Eroticism and graphic violence are interspersed with poetic dreamlike sequences, as when Fran and Miriam, after showering away the blood from their latest victim, flee to a nearby cemetery (Denham churchyard) at break of dawn.
A novelisation was published in 2001 by Tim Greaves, a fan of the film.
