北韓，當今世上最神秘的國家，「謠言」似乎已是常態。自領導 人金正恩上台後，不時傳出處決高官，連親信都驚傳被換掉或人間蒸發，讓有關核武、垮台、勞改營、饑荒、逃亡種種臆測甚囂塵上。《雲之子最後的殖民地》西班牙哥雅獎最佳紀錄片導演Alvaro Longoria決定撇開主流媒體的角度，透過與朝鮮委員會友好的西班牙代表Alejandro Cao de Benós 的協助，親身走進共產主義的封鎖鐵幕國度，真正體驗自稱為最幸福國家的北韓不為人知的一面，又請來朝鮮真正的專家包括人權、外交以及宣傳專家見證，揭開西方霸權主導下被抹黑的朝鮮，讓觀眾發現一個真偽難辨的現實謊言‥世人只是政治宣傳的最終受害者。

Through his acquaintance with the North Korean government’s sole foreign worker, Spanish filmmaker Alvaro Longoria (Sons of the Clouds: The Last Colony) gained unprecedented access into the hermit kingdom to shoot this documentary about how propaganda distorts our conception of the truth. Exploring the ongoing propaganda war between the North Korean regime and the West, Longoria analyzes how lies, false reports and half-truths are perpetuated by both sides and offers a balanced perspective through interviews with North Korean citizens, regional specialists and regime critics, letting audiences decide for themselves the results of this Propaganda Game.
