- A kind, small-town doctor mistakenly ingests pills made from vampire bat blood and they turn him into a dangerous fanged creature.
- Dr. Matthew Campbell has been experimenting on methods to regress the mind to primitive instincts so that we can find methods to improve our brains and not get taken in by cheap horror movie hogwash. He's developed a drug made from vampire bat blood and has begun treating himself with it. But instead of improving his mind, he's become ill and addicted. He dies, but not before trying to warn fellow doctor Paul Beecher. Fortunately for us, he dies before he can say more than that pills are to blame. While still at Campbell's house, Paul finds a bottle of pills and pockets them. He's also got another bottle of pills in his other pocket that he takes for frequent migraine attacks. He goes home, puts his jacket on a rack, and then he's struck with a migraine. He asks his daughter to give him the pills in his jacket pocket, and of course she gives him the pills of evil. He is instantly addicted and he must take one pill every day. Each time he takes a pill he turns into a hairy and very insane killer, and he doesn't remember what he's done, except as a vague dream. Can the police and the other scientists who work nearby figure out who the killer is and stop him before he kills the beauteous new nurse that he has just hired?—Jim Knoppow

- Just before Dr Matthew Campbell [Wood Romoff] dies, he passes on the product of his long years of animal research to Dr Paul Beecher [John Beal] . "It's the pills," he whispers. When Beecher gets a migraine, his daughter Betsy [Lydia Reed] mistakenly gives him one of the pills. That night, Beecher sleeps soundly but Marion Wilkins [Ann Staunton] is bitten by a vampire. When she is examined the next morning by Beecher, she gets hysterical and has a heart attack.
Dr Will Beaumont [Dabs Greer] comes from the university to investigate Campbell's work. He knows only that it involved base instincts and some sort of addicting pills that change the brain chemistry after only one dose. The pills must then be taken every 24 hours or the 'animal' goes crazy. More people begin to die. They all have two puncture wounds on their throats and appear to have died from 'capillary destruction'. Sheriff Buck Donally [Kenneth Tobey] gets suspicious and exhumes the bodies only to find them in a severe state of 'cellular destruction'. Some virus, apparently introduced by the neck wounds, is eating their tissue.
Beecher suspects himself. He asks nurse Carol Butler [Coleen Gray] to keep him company one night but gets called away to surgery. At 11pm, he transforms into an ugly caricature of himself. He follows Carol home but she gets away. The next night he stays with Beaumont but, when Beaumont takes away the pills, Beecher goes crazy and kills him. The next morning, Beecher decides to kill himself. Carol shows up early for work and tries to stop him. When they fight, Beecher transforms. He pursues Carol into the forest; Donally pursues them both. Beecher is shot 3 times by the deputy as he struggles with Donally. [Original synopsis by bj_kuehl]
