A meteorite crashes down somewhere in Mexico! No! This isn't a meteorite! It's a spherical thingy from outer space that makes sizzling noises!
A father daughter/pair of not clearer defined scientists goes to investigate some old ruins in the mountains and/or the crashed thingy. Since this is a Mexican film, they'll need the help of an expert. Alas, no luchador is available, so they rope in Doctor (as the titles say) or Professor (as the dialogue and Internet sources say) Zovek, a famous escape artist who is also a proficient martial artist and expert in mystical prophecies. Also, he's really good at running away.
The last talent will be of invaluable help in the future, when the sphere turns the dead into zombies, who do kid-friendly (no gut-munching, sorry) zombie things, like shambling, shambling and wrestling with people who don't run away fast enough. They also have a weird proclivity towards the stealing of cars and helicopters.
Fortunately, conflict-averse Zovek isn't the only hero on the case. Blue Demon himself sits in a cellar/secret lab and analyzes the situation for people we've never seen before and will never see again. In his time with Santo, Blue has not only learned amazing facts about UFOs and the dissection of corpses, but also that it is much better to let someone else do the heavy lifting and just sweep down in the last few minutes to grab the glory. This would be a great plan, if not for Zovek's amazing abilities. Oh, Blue also has his own "comical" side kick now and I gotta say, this man knows how treat them! If Blue isn't just treating the man as if he wasn't there, he tells him to shut up or (even better) to shut up or Blue himself will shut him up. Thank you, Blue!
When his appearance on the scene of the action can't be avoided any longer, Blue wrestles a big black guy and a wolfman. No, I don't know where those guys come from. At the same time Zovek kills the alien sphere with a conveniently located utility pole. The end.
This might just be the case of a film with a much more interesting background story than the thing itself is.
Zovek was a real life escape artist and somewhat of a star in Mexico at the time. After our old friends, Senores Cardonas junior and senior, had made the first film of a projected series of Santo-esque proportions, they at once started out on the next film with their new superstar, his complete lack of talent or charisma notwithstanding. Unfortunately he died after completing about half of a film (and this is half of a film by standards of the not necessarily filler free films of the Cardonasses). Obviously, no good cheapskate producer could let this much material go to waste, so they did the best thing that was financial possible. They engaged beloved luchador Blue Demon for about two days of shooting, the first one consisting of Blue Demon boring us to tears by talking, talking and talking in his lab like a living encyclopedia of useless knowledge, while the second gifted the film with a fight scene having nothing whatsoever to do with the rest of the film.
Or, let's be honest, what the regular watcher of late period lucha epics tends to call a film. See Zovek! See Zovek run! See Zovek climb! See Zovek look mystical (that is, rather constipated)! Also, see a few other people walk around! See zombies shamble!
Now I must admit I wasn't as bored as I make it sound. The casting of Blue Demon as scientific mastermind does have something and I must admit and one or two of the zombie scenes could be called atmospheric when you squint. Also, the film has zombies in it.
Highly recommended if you're like me and want some day be able to say: "I have seen all Mexican wrestler movies there are. Plus all Mexican escape artist movies, and the crossovers."
