The proposed agreement could dismantle nuclear weapons, but the negotiations unfold under mounting pressure and with the possibility of disaster always close at hand.

The film’s setting includes Reykjavík, Iceland, and its central conflict is political rather than battlefield-based. Reagan and Gorbachev must navigate a tense struggle in which diplomacy carries consequences for the wider world. The story also includes figures from both American and Soviet political circles, including George Shultz, Nancy Reagan, Raisa Gorbachev, Edward Shevardnadze and Paul Nitze.

What to expect

The film is positioned as a serious Cold War-era political thriller with historical and war-drama elements. Viewers can expect a story built around high-stakes diplomacy, nuclear disarmament and the pressure surrounding negotiations between major powers.

Its premise suggests an emphasis on political decision-making and verbal confrontation rather than conventional combat. The 1980s setting, the Reykjavík connection and the use of both English and Russian place the story firmly within an international Cold War context.
