Undercover Taxi.

The main participant in the secret police experiment "Undercover Taxi" Alexei Turbin enters into a deadly battle with a gang terrorizing the city. Every day he patrols the streets in a specially equipped taxi and simultaneously conducts a personal investigation. Colleagues consider the Turbine to be a magnet for trouble — because it constantly finds itself in the epicenter of events. But it is this quality that helps him solve the most complicated crimes.
