The Unearthly

At his psychiatric institute, Dr. Charles Conway (John Carradine) is surreptitiously experimenting with artificial glands to try to create longevity; he works with his minion Lobo (Tor Johnson) and his assistant Dr. Sharon Gilchrist (Marilyn Buferd). Conway receives his test subjects through an associate, Dr. Loren Wright (Roy Gordon), who delivers patients seeking treatment for lesser conditions. After this, they are then taken into the operating room for Conway's illicit surgery.
