Blood Thirst, Vampire in The Philippines?

Vampire in The Philippines? Looks that way. In 1971's "Blood Thirst," the blood sucker isn't the only social deviance preying on this Asian cluster of islands. Beautiful women in Manila are having their blood drained, but should we rush to judgment and blame vampires? One who understands Manila, and its intricacies, knows that there are a thousand other things that could be draining blood from nightclub babes.  Like what? Well...you know...

Rourke and Insp. Ramos

Sultry women working at The Barrio Club in Manila are getting murdered. They are found hanging upside down with their arms slit and drained of blood. Police Inspector Ramos (Vic Diaz) summons Adam Rourke (Robert Winston). Rourke is an American and an expert in sex murders. Rourke looks like he has a bit of sex-crazed killer in his genes. After he meets Ramos' sister Sylvia (Ketherine Henryk), it is obvious she doesn't like him or his arrogance. Not to be denied, Rourke slaps her silly a couple of times, grabs her, plants a big unwanted kiss on her and engages in some rough pre-marital sex with the nubile sister. After that, she can't get enough of him or more pre-marital sex with him. Meanwhile, more nightclub babes are murdered and drained. Rourke believes the suave and mysterious nightclub manager, Calderon (Vic Silayan), is the culprit.

Serena

After slapping Sylvia silly some more, Rourke goes undercover in the club. All signs point to Calderon...but wait! A very ravishing blonde exotic dancer, Serena (Yvonne Nielson), tells Rourke that she must talk to him.  Apparently Serena has incriminating evidence against Calderon. As more murders occur, we see the killer, a monstrous human like creature with a head covered in boils. Rourke knows he can't trust the beautiful exotic dancer, but is drawn to meet her anyway. His girl-toy Sylvia, unbeknownst to Rourke, is the next target for this creature.

Sylvia in much peril

Is Calderon involved in these murders? Just what is this monster, and why is he draining the babes of their blood? What is the mystery of Serena, and what does she have planned for Rourke? Does Sylvia need a wedding planner or the phone number to a battered women's shelter? A man's movie no doubt, and probably a favorite film of NFL running backs, "Blood Thirst," directed by Newt Arnold, and filmed entirely in Manila, is a minor gem from the 1970s.
