INVASION OF THE BLOOD FARMERS

In the small town of Jefferson Valley in Downstate New York, a number of civilians start going missing over the course of a few weeks. One day, a man covered in blood stumbles into the bar screaming before abruptly collapsing and dying. During the investigation, local scientist Roy Anderson discovers that the man's blood cells have been reproducing at an impossibly fast rate.

Later that day, a strange man dressed as a farmer approaches the house where Roy lives, only to be chased off into the woods by Roy's dog Buster. The farmer beats Buster to death with a cane in self-defense, but unknowingly drops a mysterious antique key whilst disposing of the dog's body. The next morning, Roy's daughter Jenny finds Buster's body strung up outside their front door. Jenny's fiancé Don runs off into the woods to try and find the culprit, and finds the key the farmer had dropped.

It is revealed that the farmer, named Egon, is part of a group of druids known as the Sangroids. Their leader, Creton, is planning to resurrect their dead queen, Onhorrid, by kidnapping civilians and taking them to the farm where they hold their meetings before draining them of their blood and pumping it into the queen's body, after which she will be restored to purity with the help of a "host" that the Sangroids have yet to find. Creton scolds Egon for losing the "Key of Menanon", which is an important item needed for the resurrection process. Don shows Roy the key he found, Roy calls a friend named Kinski to identify the type of metal the key is made from, not knowing that Kinski is actually one of the Sangroids (who also goes by the name of Sontag). After convincing Roy that the key is merely a cheap toy, Sontag takes it back to Creton.

The next day, Roy shows Don that he has discovered that a mixture of "iodine and household ammonia" causes the blood cells of the dead man from the bar to shrink at a rate just as fast. Whilst on a date, Don and Jenny are then kidnapped by the Sangroids, who plan to use Jenny as their "host" for the queen. Roy learns of their kidnapping, however, and tracks down the Sangroids at a quarry, where the queen is resurrected. Roy dumps a sample of the mixture onto the queen, destroying her and killing the Sangroids.

Roy uses a scientific mixture to destroy the resurrected queen and kill the cultists, putting an end to their blood rituals.

The finale unites folk horror with a dash of mad science, as Roy's discovery proves the undoing of the cult's supernatural ambitions. The destruction of the queen and the Sangroids signals both a victory for small-town resourcefulness and a wry comment on science trumping the occult. The ending is definitive—the threat is neutralized and the cycle of ritual sacrifice is broken.
