This is the strange story of an Englishman who in his lifetime lived in the world of the ghostly caveman...
The Heap [Baron Eric von Emmelman]; Jeffrey Vassily; Rok-ta (Neanderthal man); Mr. Oxham (Jeffrey's guardian, death)
A young boy, interested in continuing his father's work on the Neanderthal Man, must deal with an unjust guardian who has anything but the boy's interests at heart. The young man, considered a weakling, personally researches primative man's mystic ritual of strength, and meets Rok-ta, who turns him into "A Man of the Caves": a primative himself! He kills his guardian, but then he meets the Heap!
