The Earth of the future has been divided into two parts-the developed World of Order and the backward World of Decadence. These worlds have abandoned contact with each other and built Walls between them. World of Order is the modern, technologically developed world, where is no crime, wars, and any kind of conflicts. World of Decadence lives in the past denying all the progress, technical development, and modern values of the World of Order. Jerry Kaiser, a refugee from Decadence, writes virtual reality programs, which are created to the customer's taste. They are filled with psychodromes, emotions recorded in a digital format. Commissioned by Richard Kamer, one of the Devil's Dozen, the ruling elite of the World of Order, the head of a ministry without a name who is responsible for top-secret, inter-world relations, he creates a horror program that Richard uses to kill the most influential citizens of Order. Jerry is found guilty of these murders. Jerry finds out that the victims of the program are connected to the dark secret organization - Trails de-Hell, where the immigrants from the World of Decadence and dissidents of the World of Order are killed, tortured, and hunted. The one existence of Trails de-Hell makes World of Order not that ideal and utopic as it seems. Jerry wants to unravel the secrets intensions of Richard Kamer and realizes that he is the one who intends to lead the world to the big changes. But to succeed in it, humanity will need to make huge sacrifices, and Jerry will have to take sides.
