It's a simple story about a group of people who are trying to kill a very powerful vampire named Nostradamus, played by Robles.
This is edited from a serial and so it moves along rather quickly. This is the third of four features edited from said same material. Jack Taylor stars in this as Igor, and no he is not a monster, he is a scientist who is trying to kill the vampire.
Someday I would really like to see these in their original Spanish language versions, as the US dubbing leaves a lot to be desired. Good stuff however, and worth seeing.
