It is wartime and John Ridgeforth has been smuggled, his mission deadly secret, into a country which he thought he knew, thought he loved. It is a country where public lynchings are condoned; where concentration camps are rife; where neighbour spies on neighbour, and lovers are dangerous enemies; where Jews, Blacks, Communists are branded with the letter K. A country where K stands for kike; and for the Ku Klux Klan.

K carries us into a nightmare world which is also uncannily close to truth and our worst fears, most haunting dreads. We have seen fanaticism; now we see what could so easily have been all our yesterdays.
