The TV series "Lihach" is an adventurous detective story about the work of the Sochi criminal investigation department. Sergey Sotnikov is the deputy head of the police department who loves two things the most: sending criminals behind bars and driving fast through the streets of his native southern city. That's why his colleagues call him "Lihach" (Speedster). One day, Sergey is offered the position of chief, but he refuses the promotion because office work is not his thing. Chasing robbers, tracking down killers, and risking his own life - that's his calling.
