Neanderthal Man

What primitive passions...what mad desires drove him on... Nothing could keep him from the woman he claimed as his own! - A scientist who works in his home lab out of town is rejected by his colleges at the Naturalists' Society when he presents his theory that the size of skull and brain equate with intelligence, and therefore Neanderthal man was equal, if not superior, to Homo sapiens. After his professional rejection the scientist rejecting his fiance and filled with mad desire secludes himself in his lab where he develops a serum that turns himself into THE NEANDERTHAL MAN.
