Prime Minister Thorbjörn Fälldin quickly heads down to Stockholm and the Government Office, where he gathers representatives from the government and the military. Meanwhile, the situation for Captain Peskov and his crew is becoming increasingly desperate.

Captain Peskov receives orders from the Kremlin to blow up the submarine if the Swedes try to get on board.

Prime Minister Thorbjörn Fälldin meets the Soviet ambassador Aleksandra Kosygina. It turns out that their plan to have a radio mast installed on the submarine is thwarted by Commander-in-Chief Lagercrantz, who has exactly the same plan, but with completely different purposes. In the Kremlin, the frail chairman Brezhnev finds it increasingly difficult to manage the situation, but receives unexpected help from the KGB's Yuri Andropov.
