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. Professor Groves, an expert in prehistoric life, proves his theories with an extract that'll regress a cat to a saber-tooth tiger and man to a Neanderthal.
