The series \"Police Academy\" already gives its name to the plot basis of the picture - the main characters will be representatives of the preparatory police unit. The first thing we will get acquainted with is a detective who puts a lot of effort into catching a dangerous criminal. On the other side of the barricades, a hacker is working, who faces a particularly difficult task. He wants to reveal all the secrets of modern society by hacking servers. These two things collide at the national academy. One of the characters acts as a professor who teaches important disciplines to his wards when the second becomes his student. Yu Jong Man has already twenty years of experience in various departments, so his experience cannot be ignored. Kang Song Ho is a representative of the cyber department, who manages to find not only useful knowledge, but also true love. Oh Kang Hee is a freshman girl who has always dreamed of becoming a police officer. She was different from her peers. The latter dreamed of becoming Disney princesses, when the main character really wanted to get a chance to become a representative of the police. The most desired gift at the age of twelve for the heroine was handcuffs. It is also worth noting from the acting characters of the charismatic Cho Joon Wook, who has been abroad for a long time, but finally returned to his homeland in Korea to start life almost from scratch.
