In one city near Moscow, on the eve of the New Year, senior investigator Alena Igorevna Ivanova is trying to sum up the results of the year. But fate again and again gives her a chance to be convinced of the truth - everything in life is temporary, nothing will last forever. It is not possible for a person to know in advance how his action will affect another person, how it will change his fate, how a good deed can turn into mortal danger, and how inner convictions and high moral aspirations give way to vice and evil, how reckless courage can be the product of fear and despair. The criminal cases that senior investigator Ivanova investigates every day make her think about eternal issues and life values, when human relationships come to the fore.
