At the presentation of the entertainment center "Far Away Kingdom" a tragedy occurred: the roof of one of the pavilions collapsed. People were injured, including relatives of the criminal authority named Zubr. Suspecting that this is a terrorist attack staged by Caucasian or Central Asian criminal groups, Zubr declares war on them. Colonel Gurov, who has begun to investigate the case, prevents bandit slaughter by promising to find those responsible within ten days. Gradually, investigators come to the conclusion that this is not an ordinary gangster showdown - a complex explosive device made by a professional of the highest class really worked in the pavilion. To calculate such a specialist is not just a matter of honor for an important detective, but also a task of national importance.
