January 1916. The First World War is in full swing, and it is not surprising that near Trabzon, in northeastern Turkey, it is “hot”, although the winter turned out to be cold. The local Greek population, exterminated by the Turks, rebelled. The partisans hiding in the mountains eagerly await the arrival of the Russian army advancing from the Caucasus. Meanwhile, Lieutenant Colonel of the Turkish Army Karadyumak Sahin, with the ingenuity of a true maniac, continues what he has been doing since the beginning of the war. There is no end to the robberies, murders and violence, so some of Shahin’s subordinates no longer want to obey orders, there is no moral strength. However, this horror can only be stopped by those in whom true anger has awakened - the anger of the Black Cobra, a peace-loving snake, but terrible if angered.
