Future border guards come to the National Academy of the State Border Guard Service of Ukraine for different reasons. The cadets' mentor, Ivan Krynytskyi, uses his own method to turn yesterday's "yard boys" into real combat officers.

The ATO veteran, Major Ivan Krynytsky, returns to civilian life in the summer of 2021 and becomes a course officer at the National Academy of the State Border Guard Service of Ukraine, whose graduate he is. Krynitsky recruits a special group to pass on his combat experience to the next generations. Young cadets who get to the Krynytsky group have very complex training and testing, unlike other cadets. Will they be able to accept the rules of their strict Major, or will it be easier to get him out of the Academy?
