Within the earth's core, lives an advanced race who have created an offspring. This offspring (the Dweller) gradually turns from good to evil, and at times will rise to the surface of the earth to capture men and women. Scientist Dr Goodwin and pilot Larry O'Keefe follow the Dweller down and O'Keefe finds himself caught between the attentions of two beautiful women; one good, one evil.
