This film highlights the complete ignorance of both Hollywood and the State Department when it came to analyzing events in both China and Mongolia in 1949.
Initially, the US sided with Chiang Kai-Shek and the Chinese Nationalists at the start of the Chinese Civil War with the Chinese Communists and Mao. The KMT controlled the cities, and the CCP controlled all the areas outside of the cities.
Mongolia was taken back from Japan by China in 1945, but since it was far away from any major Chinese city, it inevitably fell into CCP hands. The actors give it their best, but no one could rescue the poor production values, the preposterous script, and the corny dialogue that composed this turkey. Better to spend some time on YouTube and research the actual events of the Chinese Civil War.
