In the area overseen by Major Nachalov, there is a clandestine laboratory for the production of methamphetamine. People are dying from the “scorched” drug. Cadets of the higher educational institution of the Ministry of Internal Affairs - Kharlamov, Krechetov, Tsarev and Ushakov are finishing their studies, there are a few days left until their diploma. Zhenya Krechetov has a whirlwind romance with Nachalov’s daughter, Nadezhda. Cadet Kharlamov allows a conflict with the leadership, as a result of which he is under threat of expulsion. Major Nachalov, at his own peril and risk, takes the cadets to his new department, killing two birds with one stone - he saves the guys from trouble and gets new, not exposed and not corrupt employees.
