Cal, Veg, and Aquilon- two men and one woman- roamed the alternate dimensions of time and space. With them were the mantas, strange flying aliens- half animal, half fungus- who could boost the keenest senses of any creatures in the universe. And with them too was the mysterious, impassive superwoman, Tamme.

They were imprisoned on a hostile world dominated by savage robots. It was crucial to their very survival that each find a way back to their familiar dimension of Earth.

Suddenly they encounter OX- an amorphous, telepathic being of brilliant luminosity- who held the key to every alternate continuum in the universe, including their only chance of escape!
