Plowing the dark

On the west coast of America, virtual reality researchers race to complete the Cavern, a plain white room that can become a jungle, a painting or a vast Byzantine cathedral. Adie Klarpol, a disillusioned artist, is fascinated by this cutting-edge technology. In a war-torn city on the eastern shores of the Mediterranean, an American teacher - Taimur Martin - is held hostage, chained to a radiator in an empty white room. What can possibly join two such remote places? Only the shared imagination, a room that these two people unwittingly build in common.
