The Fourth Protocol (1987) HD

Storyline: In 1968, the United States, Great Britain and the Soviet Union signed a nuclear non-proliferation treaty, signing a highly secret part of it, classified as the "fourth protocol". But is there anyone who bothers to violate precisely this part, in an era in which, despite all improbability, the assembly of the various elements making up a one-kiloton atomic bomb is not a difficult operation, destined to blow up everything which can exist on two square kilometers of territory. That someone is a general, president of the KGB, for whom an explosion at an American base on British soil would be the ideal incident to unleash a wave of resentment against the United States. Once the so-called "Aurora plan" was set in motion, operational responsibility was given to a Red Army officer - the shrewd spy Petrovsky - who installed himself near the base in question to receive both the messages and the various pieces intended for the terrifying composition, brought to him by illegal immigrants arriving from individual countries beyond Cortina. It is up to John Preston, a British counter-espionage agent, reckless and a little recalcitrant to orders, but energetic and very suited to the mission assigned to him, to locate his adversary who, among other things, has orders to litter his own area with corpses. journey, including soldiers and agents of the KGB itself. The conclusion will be dramatic, but the "Aurora plan" will be foiled in its intent.
