The film is set in Karafuto after the radio broadcast of the Imperial Rescript on the Termination of the War. On August 15, 1945, Soviet forces invaded Karafuto. On August 20, the postal telegraph office in Maoka suspended operations and nine of the twelve telephone operators committed suicide by taking potassium cyanide while the city was being invaded.
