The central character is Yulia Loginova, a dentist and aspiring detective author. Her first book was published and immediately found a reader. Fans are eagerly awaiting her next novel. Yulia's young man, investigator Denis Potapov, is convinced that the book turned out so well thanks to his stories and recommendations. He wants Yulia to make him her co-author. Yulia refuses, they argue, and Yulia is left without Denis' stories, and consequently, without a new book idea.
