State School 4 is a classified Russian specialist training school for "Sparrows", SVR agents who are trained to seduce their targets with sexpionage. Located in the Russian countryside, the school's cadets were mostly female Russian Army soldiers who entered the intelligence corps, but there were also male cadets. The cadets were trained through exercise jogs, a firing range, watching hardcore pornography, deducing what a person "wanted" in a sexual relationship, being exposed/raped in front of the class, and watching other cadets' filmed sex lessons to evaluate them. The agents were therefore deprived of their personal freedoms and turned into agents of the state, and the school produced several talented SVR agents. One of them, Dominika Egorova, would later defect to the United States after being assigned to honeypot CIA agent Nate Nash in Budapest, Hungary.
