There is a gang of villains roaming the city that kidnaps scientists
involved with some disintegrator ray, and a few bankers on the side, too,
who are then made to rob their own banks. Masked investigator El
Enmascarado (Santo) is on the gang's trail, but he is overpowered and put
under some hypnotic spell, and from now on he works for the gang.
Zambrano (Enrique Zambrano) figures the gang will go after Doctor Campos
(Joaquín Cordero), another scientist involved with the disintegrator ray,
next, and puts him under police protection - not knowing of course that
Doctor Campos is the baddie of the piece, kidnapping all these scientists
to sell the disintegrating ray to a foreign power. Doctor Campos has only
one weakness, Eliza (Norma Suárez), girlfriend of his assistant Gerardo
(Alberto Inzúa), who is your typical all-around good guy who actually
doesn't do very much though to keep the story moving. Eventually, Doctor
Campos has Eliza kidnapped, which somehow gets the police wondering ...
El Incognito (Fernando Osés), another masked police investigator, who
manages to break into the hideout of Doctor Campos' gang, defeat the still
hypnotized El Enmascarado, and inject him a serum that gets him back to
normal. However, the two decide it's best for El Enmascarado to continue
to pretend to be under hypnosis to keep a close eye on the gang.
El Incognito brings the police to raid the gang's hideout, and with the
help of El Enmascarado, who pretty much attacks from behind, the gang is
put out of commission. Only Doctor Campos manages to escape, with Eliza as
his hostage. Ultimately, he manages to lock himself inside his house and
keeps the police at bay by threatening to kill Eliza. But then El
Incognito manages to distract the baddie long enough for El Enmascarado to
break into the house and overpower Campos before he knows what's happening
A remarkable film inasmuch as it is the first movie to
star Mexican wrestling superstar El Santo - even if his role seems to be
somewhat secondary at closer inspection. Still, Santo would go on to make
dozens more movies over the next 25 years.
Apart from that, Cerebro
del Mal is pretty much your typical gangster-drama with an espionage
and some light science fiction thrown in for good measure. It's
competently made but sure enough shows its budgetary limitations, and if
the two masked men make sense within the plot is at least debatable. The
film does feature some beautiful shots of pre-Castro Cuba though ...
