Dracula, or Alucard as he's called here gets himself a Wolfman, or a Jackal-Man as he's called here, servant to get him some ladies for his blood drinking and sexual needs. So it's sorta like that Bela Lugosi movie RETURN OF THE VAMPIRE except this is way more of a softcore porn situation where our vampire villain has sex with, aka rapes, naked gals while still completely dressed using some weird, rarely seen vampiric powers. Also it's dubbed to make it a comedy giving Drac a very Jewish accent and also strangely giving one of the ladies here an old grandma voice.
Apparently Woody Allen's first movie WHAT'S UP TIGER LILY?, made a few years earlier and similarly dubbed except a bit wittier, was enough of a hit that this was made along the same lines. It is pretty humorous for about half the movie then it starts to get a bit monotonous but still worth a look for lovers of obscure weirdness. Tits are bitten, Irving Jackal-Man gets in on the raping, women are insulted(or fat-shamed as all the sensitive types call it now) and it ends in a monster brawl.
