The memorable catastrophe in the Chernobyl power plant took place on 26th April 1986 at 1:27 am, affecting the lives of over 300,000 people inhabiting the surrounding areas of the then USSR territory in a direct and immediate manner. The long-term consequences of the released radiation, the biggest in the history, are being felt to this day and are expected to be still harmful for human health in the next decades. The docu-drama reconstructs four days following the disaster from the point of view of the Polish communist political and military circles, alarmed by the medical scientific center in Warsaw, as well as the reactions of foreign journalists based in Moscow. Poland, the first country on a way of the radiation cloud, was nervous about the possible harm it might cause among ordinary people on the one side, on the other however – wasn’t sure how to react politically in a face of continued silence and disregard of a danger of the USSR authorities.
