His successor Dr. Fred Stiller experiences odd phenomena. A good friend, Guenther Lause, disappears in the middle of a conversation and a week later nobody has ever heard of him. And those fits of dizzyness - Stiller cannot believe himself to be fool. There has to be an explanation for all this. Could Simulacron have something to do with it?
