The documentary sheds light on the grueling diplomatic process that culminated in the signing of the Helsinki Final Act in 1975, after years of talks. The film draws on long-secret transcripts of the talks and uses artificial intelligence to recreate the voices of General Secretary Leonid Brezhnev, US National Security Advisor Henry Kissinger, and other politicians. The result is a fascinating look behind the scenes - at the vanities and oddities of diplomatic theater. A complex topic explored here in a clear and accessible way. Heads of state from 35 countries were present. While the Soviet Union pushed for recognition of the borders established after World War II, Western Europe and the US fought for democracy and human rights. After tough negotiations, the 35 heads of state finally agreed on a compromise - a diplomatic balancing act that had far-reaching consequences.
