In the center of the plot is the sweet and charming Olga Dudkina, who works in a taxi. The real angel Kostya falls in love with her and persuades heaven to send him back to earth. Dudkina gets the ability, like Kostya, to see the restless souls of the dead, and together they begin to help correct the mistakes of the past.

Among the "clients" are an oligarch guilty of raising his son, someone's annoying neighbor who drills day and night, and even Dantes. The problem is that all the temptations of the modern world are falling on Kostya at once. And instead of accepting angel's attentions, Dudkina has to fight to keep him from going to hell.
