Senior Investigator for High-Profile Cases Nikolai Savelyev decides to retire. He needs to sort out all his personal problems – his impending divorce from his wife, his son, who is a student, and take a break from his tiresome job. Unwilling to part with such a valuable employee, his boss deliberately delays signing the resignation form. Savelyev heads to his hometown – the provincial town of Stepanovsk. Here, on the forest border named after him, far from bustling Moscow, Savelyev hopes to reflect on his life so far. However, whilst sorting out his personal and family matters, he also has to untangle numerous cases regularly thrown his way by his superiors, acquaintances, and friends.
