The author reports on the secret submarine operations of the USA and the Soviet Union, including "risky espionage missions by US combat swimmers in Soviet waters", which resulted in numerous fatal accidents. Both "superpowers" are also said to have lost submarines in various missions due to accidents or collisions. In the film, Pohlmann gives a voice to Ola Tunander, a professor at the Institute for Peace Research in Oslo at the time, who is "certain" that "the alleged Soviet submarines that were unsuccessfully hunted by the Scandinavians in the early 1980s were actually part of the Americans' psychological warfare". The "common goal of some very senior Swedish officers, the British Thatcher administration and Ronald Reagan's policy" was "to discredit the Olof Palme government and its initiative for a nuclear weapons-free Northern Europe".
