Labrador Trison now has two charges at once - the veteran of the Ministry of Emergency Situations Vladimir Petrovich and the German shepherd Fukushima. Both were blinded by a strong fire. With the advent of Trison, their lives changed dramatically: Petrovich began to go out and finally gained freedom of movement, and Fukushima had a real friend. Thanks to the devotion of a smart and quick-witted Labrador, the man and the dog were able to enjoy life again. And everything would be fine, but only Trison periodically has to defend himself from the harmful cat Pharaoh, help Petrovich improve his personal life and protect Fukushima from the ridicule of other dogs.
