On an expecition to Tibet, Doctor Waldemar Daninsky (Paul Naschy) has
been bitten by a Yeti, and since then he carries the sign of the Pentagram
on his body, which according to horror logic makes him a werewolf.
However, he can supress the urges to turn into a wolf ... until his wife
(Diana = Pilar Zorrilla) and her lover try to murder him by severing his
car's brakes. He survives the crash that should have legally killed him,
turns into a werewolf, returns home to kill his wife and her lover, and is
then accidently electrocuted himself.
And that's that ?
Not by a long shot, because Waldemar's best friend, a certain Doctor
Ilona Ellman (Perla Cristal) - the only person Waldemar ever confided to
concerning his little werewolf problem - decides to dig up Waldemar's
corpse, somehow bring him back to life, and make him into a superior being
that she somehow mindcontrols. Of course, the experiment eventually gets
out of hand because in his wolf-form, Waldemar resists (almost) all
control and turns into a vicious killing creature, while in his human form
he tries to escape Ilona with the help of her assistant Karen (Verónica
Luján) who refuses to any longer be a part of the Doctor's mad
experiments. To keep Waldemar in line, the Doctor even resurrects his
wife, who has meanwhile turned into a werewolf as well.
It all ends with the Doctor and Waldemar being at each others throats
and kill each other, before the police and Doctor Ilona's dad Doctor
Wolfstein (Javier de Rivera) make it to Doc Ilona's place to save poor
Karen who has since been chained to a wall (don't films like this always
need a girl chained to a wall ?).
Of course, this film is silly as can be, filled with outrageous
elements like mutants, science gone wild, brutal slayings and the
obligatory girls chained to walls, and of course this is not what you
would call a good film as such. However, if you are into trashy
Euro horror from the 1970's as much as I am you will still like this one
despite of or even because of its shortcomings like its inconsequent
screenplay, its very spartan direction and its not too convincing special
effects. It's just good, completely mindless fun, and that's all that
