The film is dedicated to the students of the recently opened Sergeant School, based on Ryazan Paratrooper Command School.
Main characters are three students — Alexei Yefremov, Yevgeny Fyodorov, and Maxim Prudnikov.
They tell how they got in the army and why they entered the Sergeant School after so many years as civilians. How entry exams, that turned out to be a tough trial, went, and what hardships they had to overcome.
The crew spent with the students a few days and followed through their life from reveille to evening leave, from everyday lessons to skydiving and military exercises.
