Plot

An unknown group, calling themselves "Temnaya Loshadka" ("Dark Horse") routinely assassinate inconvenient people. Everyone from federal security services to victims' friends and a local policeman try to tackle them.

There is a certain brigade that calls itself the "Dark Horse". The specialization of the brigade is the elimination of persons objectionable to it, and the methods for this are chosen in a variety of ways. Both the relatives of the victims and Interpol itself are knocked down, but looking for the criminals they are unable to stumble upon their trail.—Tango Papa
