Andriy Skovoroda, the charismatic and unconventional head of the Criminal Investigation Department, is put in charge of a team of inexperienced recruits. He finds himself at a police station on the outskirts of Kyiv and is forced to teach his subordinates not only how to catch criminals, but also how to connect with people and communicate—even though he himself is indifferent to social interaction. The major is known for his sarcastic humour, philosophical quotes and unexpected methods — he is more like a teacher or even a nanny than a strict boss.
