The series is set in a dystopian future in which Britain is under the grip of the Home Office's Department of Public Control (PCD), a tyrannically oppressive bureaucracy riding roughshod over the population's civil liberties. Edward Woodward plays Jim Kyle, a journalist on the last independent newspaper called The Star, who turns renegade and begins to fight the PCD covertly. The officials of the PCD, in turn, try to provide proof of Kyle's subversive activities.
There's good news and bad news in Britain. The good news: Home Secretary Dan Mellor has been replaced by Kate Smith, and a "pentagon" - one of a growing army of dissident groups - is preparing to take on the hatred PCD. The bad news: the PCD's new Deputy Controller is Lynn Blake, Jim Kyle's former romantic interest, and her first job is the exposure of "Faceless", Kyle's source within the PCD.
"This mate of yours is a shark. With his jaws into whole cargoes. Petrol. Fags. Booze. Grub. It's up to us to nanny him?". When food available in the supermarkets steadily evaporates, Kate Smith's government turns their attention to black marketeers profiting from illicit supplies. Ministry of Food MP Peter Greville feeds Kyle information about the matter, but soon both he and his family become the focus of suspicion from the Public Control Department.
"Who are we out to nail? Careguard, the Home Secretary or Skardon and the PCD?" Jim Kyle is in trouble - he has fallen into the hands of Police Commissioner Hallam.
"Authorised Systematic Harassment has enormous potential. The slow and noiseless steamroller of the State. The daily brown envelope dropping on the mat". The Public Control Department, in response to more dissident remarks printed in the underground press from Kyle and Tony Doran, devise a plan to turn the heat up on the pair by employing a systematic campaign of Authorised Systematic Harrassment (ASH). Using all the bureaucratic mechanisms at his disposal, Skardon launches a tirade of officialdom against both men, which succeeds in pushing Doran and his wife to breaking-point.
"If Kyle can uncover those extortionists where an expert PCD man failed, he is obviously implicated with them." When workers fall prey to an extortionist network collecting money in exchange for their continued silence, Kyle's involvement attracts the attention of PCD controller Skardon, who recognizes an opportunity to eliminate the network and the thorn in his side in one stroke.

"Kyle'll be back to normal in about an hour. Until then he'll probably show an amusing tendency to tell the truth." Groups of dissidents, once-divided in their opposition to the Public Control Department, are putting aside their differences in a bid to bring down the bureaucratic machine in a consolidated movement. Meanwhile, Skardon increases his pursuit of Kyle, whom he believes he can break and thereby shatter the plans of the opposition.
"We always said there'd be Peace Crimes Trials one day ... We're winning now. There'll have to be a purge of the PCD soon." The dissident assault on the Public Control Department has been successful, but the public suicide of a cell member has resulted in world condemnation of Britain's policies and the PCD being plunged into bitter in-fighting.
