The plot of the series is based on the eponymous work by writer Maria Voronova. Three years have passed since the events of the film "The Book Girl". Professor Ruslan Volchetkin continues to charm women in the hospital. The next "victim" of his charm is Inga, an attractive lady and a talented surgeon. She has almost lost hope that Ruslan will ever leave his wife, resigned to the fact that she will be a single mother and the mistress of an unavailable man for the rest of her days. That's how it would have been if Severina hadn't appeared in her life.
