According to the plot, the mayor of the city Nikolay Nikolaevich introduces his new deputy. A major specialist whom he lured from the capital. No one in the administration even suspects that just a week ago Katerina Petrovna was a tequila girl. After a serious conversation with a local authority, the mayor drinks too much and falls into a coma. Now, Katerina is the acting mayor, as that same authority decided. Katerina plans to simply enjoy life in her new status, but everything changes when she meets Sergey, a young doctor who loves his job and his Lisyegorsk. The feelings that have arisen for Sergey motivate Katerina to take a close look at the provincial city and make it at least a little like the capital.
