"Necessity is the plea for every infringement of human freedom. It is the argument of tyrants. It is the creed of slaves" (William Pitt). Home Affairs correspondent Jim Kyle, a journalist for one of Britain's three remaining newspapers, provides secret assistance to people trying to escape the repressive regime. His activities continually bring him into contact with the Public Control Department, its tools of bureaucratic repression and its ruthless Controller Herbert Skardon. However, Kyle's current attempts to help a doctor struggling to help his asthmatic daughter leave the United Kingdom may be hampered by Kyle's ambiguous personal relationship with Deputy PCD Controller Delly Lomas.
