'Zena and the boys went ice-ring planing, Boys fouled up and Earth got a raining!' Gus and Thatch were desperately trying to drive the big mobile home up into the mountains, high above the floods rapidly drowning out the rest of the world. They even had some crazy notion about saving civilization from the waters - which was why they took along uptight Zena - who knew far more than she was telling about why that vast canopy of ice had suddenly surrounded Earth - and voluptuous Gloria - who turned out sometimes to be a man and sometimes a woman as well. And then they picked up Karen, and Floy, and Dust Devil, and Foundling - two latterday Noahs in a motorized ark. The trouble was, their little community wasn't the only one frantically trying to find dry land, food and fuel. And seeing robbery, looting, murder and cannibalism were now looked on as legitimate means of survival, the struggle for life was apt to become a little vicious at times.
