The story revolves around 45-year-old Viktor Firsov, who had been working in the special forces for as long as he could remember. Even as a child, he knew he wanted to follow in the footsteps of his father, Captain Semen Firsov, who served in the OMSN (later renamed SOBR). When Viktor came of age, his father passed away while on duty. After his military service, Viktor joined the special forces and became part of the rapid response group in the Rosgvardiya command. It is widely believed that the best fighters work in this team.
