Nina Pokrovskaya is a happy wife and mother who once worked as an investigator. After the high—profile case of a serial killer, she left for her family, leaving her career to her husband, a high-ranking officer of the Ministry of Internal Affairs. But one day, while taking pictures on the street, she accidentally shoots her husband with a young girl — at the moment when he should be on a business trip. Cheating ruins a normal life. Nina leaves, taking her son, and finds herself having to start over from scratch. Perhaps this is not the only mystery she will face.
