Buxom blonde Ofelia (Susana Beltrán) is pressured by her family into marrying Eduardo, even though she loves Gustavo (Walter Kliche). What she doesn't know is that the man she really loves is actually a vampire. On Ofelia's wedding night, Gustavo sneaks into the marital bedroom as Eduardo is getting busy with his new wife, stabs the man through the neck with a dagger, and ends Ofelia's life by draining her of blood.
Later, when Ofelia has been buried, Gustavo goes to her grave to see her rise from the dead as a bloodsucker. The pair are reunited. Cue groovy, animated, psychedelic titles
Titles over, we are introduced to a group of hippies/beatniks who are on holiday, sightseeing, skiing and attending swinging parties where the women take off their clothes to jiggle their bits. While driving down a remote road, the gang's van runs out of fuel, leaving them stranded, cold and miles from their destination. Fortunately, one of the them is familiar with the area and knows of an abandoned lodge not too far away, so the group head for shelter, unaware that vampire Gustavo and his big-breasted 'bride' are lurking nearby, waiting to feed.
Directed by Argentinian Emilio Vieyra, who also gave us the bizarre cult classic The Curious Case of Dr. Humpp (1969), and the rather entertaining oddity The Deadly Organ (1967), Blood of the Virgins is packed with wild visuals, jazzy music, soft-core sex, a smattering of gore, and hot women with large breasts (Vieyra might not be able to tell a seagull from a bat, but his good taste in women is in no doubt—as well as Beltrán, there's also gorgeous brunette Gloria Prat as Laura, one of the vamps' victims), all of which makes it a reasonable time-waster despite the rather routine plot and some atrocious acting.
