Former special forces soldier Leonid Zubov works as a forest Ranger in the taiga. Together with his associates, he solves crimes related to poaching, illegal business, crime in the territory entrusted to him, and also helps residents of the local village of Olkhovka to fight emergencies and solve personal problems. A rural paramedic Vera Bolshaeva is in love with Zubov, which puts him before a difficult question-whether he is able to love another woman after the tragic death of his wife.
