History has preserved the names of heroes who fiercely defended their homeland on the battlefields, but do people remember those who acted “under the heading of secrecy”? Who guarded the borders of their beloved country from the most dangerous enemies - those who pretend to be friends, smile and swear allegiance, and then attack from behind? No, no one honors secret intelligence agents, although it is thanks to their victories that powers rise. Soldiers of the invisible front, brave and determined, they are fighting in a war that never happened. Sergei Razumovsky also chose this destiny. More precisely, he himself was chosen for a dangerous mission. To penetrate the territory of the enemy, you must take on his appearance, become a different person and renounce everything you knew and loved before. This is exactly what Sergei had to do. Yes, his lot was not easy, but at the end of the road, the most valuable of all rewards awaits him - the truth.
