Who is Marian? Is he a socialite and sexual guru, whose services are used by half of the women in the capital? A coach with controversial methods? Or perhaps simply a cunning seducer of the opposite sex? This is the mystery that ambitious tax inspector Klara (played by Aleksandra Domańska) will have to face. Will the relentless bureaucrat find the answer before she herself falls into Marian's romantic traps? And is she prepared to lose control over something for the first time in her life?
