"There are hours and minutes that change the course of history, when each second, each word and each decision are filled with an almost unbearable tension and have a bearing on the fate of not just a nation but the whole of humankind.
Zero Hour reconstructs these specific moments using a real-time split-screen format that allows viewers to experience the 60 critical minutes leading up to each crucial event."
Excellent (imo) documentary, really well done. Has (German?) subtitles.
