Shorty Martin found an alien machine on his Iowa farm by accident. He excavated it and discovered that it powered up at noon. He walked up the transparent corridor and stepped out on the sphere and disappeared from Earth.
He was transported to another planet. An old witch woman named Bitina tries to kill him. He learns her language through her magic and becomes her lover. A squad of army rangers follows Shorty to the planet. Only Dan survives. The planet was invaded ten thousand years ago by humanoids who live forever. These creatures breed human beings for food. Using Bitina’s magic, Shorty and Dan plan to put an end to the genocide.
