Richard Blade, and English gentleman, is the perfect subject for some unusual scientific experiments. In this latest one, he is sent back to the Stone Age to live in a cave with strange, otherworldly creatures. He is then confronted by fierce ape-men with a penchant for necrophilia. One slave escapes, however, and turns out to be the lovely Ooma, a Jedd, and a survivor on an all-but-doomed civilization. Blade falls in love.
But the Jedds' dying Empress wills Blade to marry they child-Princess, Mitgu. He must then lead the Jedds out of their plague-ridden valley to the Shinning Gate. This means another deadly encounter with the ape people, and other untold dangers. Blade faces his most bizarre battles in this adventure. How can one man dare to taunt the fates so often and still emerge unscathed and whole? Alone in Dimension X, naked against the unknown.
