In the waning years of the Cold War, Nicholas Foley, a Soviet sleeper agent and a survivor of the World War II siege of Leningrad, is a scientist and technological genius quietly working in American academia. He develops an ultrasonic gadget with which he can indetectably control the minds of others. His wife knows his secrets, but loves him too much to turn him over to Federal authorities.
