During the Cold War conflict, a period in which the differences of opinion between the Allied occupying forces and the Soviet Union become ever sharper, an airplane accident occurs over Tempelhof Airport during the Berlin Blockade, with grave consequences. The tragic collision of an American airplane carrying relief goods with a Russian fighter plane costs not only the lives of both crews, but also overstretches the already tense relations between the occupying forces. Under the command of the merciless Stalin, the Red Army has undergone a tremendous expansion at the end of the Second World War and has more-or-less been waiting for the right time to extend their territory to the West by attacking the NATO.
