Ivan Ivanovich Zhurov — unlucky, but very experienced detective. He travels everywhere on his old "Pobeda", one brings up a daughter, loves to drink and has very troubled amur relations with his colleague. All this does not prevent him from masterfully disclosing the most complex and tangled loud criminal cases, for which, besides him, no one more risks to take.

A novelist struggling with writer's block enlists the aid of an assassin for some inspiration -- fully unaware that he is being set up to take the blame for a murder.
