The Aruak and the Con Artist.

An aging employee constantly deceives everyone around him: clients, his boss, his wife, and his children. But at some point, it becomes too much, and they decide to punish him. A spirit named Aruak starts following his every move, teaching him to speak his native Kazakh language, interfering in all his affairs, constantly commenting on everything, and putting the deceiver into the most awkward situations.
