Konstantin Makheyev is a successful writer - he writes popular detective stories under a pseudonym. Inspiration only comes to Konstantin, however, when he is in love and his feelings are reciprocated with equal passion. However, one affair suffices him for one book only, so Konstantin needs to replace the girlfriends frequently! Konstantin is carried away with the very process of "hunting" and never gives a thought to what the women feel when he breaks their hearts. When he is planning to strike up a new affair with another “muse”, his attention is suddenly attracted by Asya, a humble girl who has just saved a homeless dog. Their first meeting seems to be a failure when they meet at the police station. However, circumstances cause the young people to constantly encounter each other here and there, so inevitably, the womanising Konstantin unexpectedly finds himself falling in love with the modest Asya. Trying to win the love of this most unusual young woman, Konstantin starts to undergo some extraordinary changes.. And later, he even gives up writing his usual profitable, but primitive, detective stories and turns his attention to writing 'A Really Great Novel'.It seems that nothing can prevent the couple from being happy together, until one of Konstantin's ex-muses appears on the scene. In addition, Asya turns out to be not quite the simple young woman she first appeared to be.
