Young, handsome and cultured Ramón goes to visit his dying grandfather on his deathbed. During the visit, gramps explains that to inherit his isolated farm he'll have to share it with his cousin Beatrice. But a dark past is linked to this estate, full of mystery, murders and unexplained, perhaps even supernatural, events.
A cheerful sweeper collects garbage dancing, and the maids of the neighborhood get jealous because he invites another woman out.
In the late 1800's, Boris Karloff has discovered a way to use nuclear power. He creates a beam weapon and blows up a big rock. Outer space aliens are scared and one alien who looks a lot like James Cameron with a big fake nose only this one isn't fake lands and brings other aliens who take over the bodies of Karloff and his assistant. The assistant is a Jack the Ripper style killer who has done a few nasty murders which have riled the townsfolk. The body-snatched bodies become radioactive and start killing flowers and other stuff (but don't die themselves) and some stuff happens and in the end Karloff destroys the beam weapon equipment (and his lab and house), then the aliens leave and warn us that if anyone ever does it again there will be trouble.
