Corrected to Believe

Marusya lives abroad with her mother and stepfather, where she was brought for treatment 10 years ago. After burying her parents, Marusya postpones her wedding and travels to Russia for the first time after a long absence. She has reason to believe that the murder of her mother is connected with their past, but the main goal of Marusya is to get to know her father, whom she did not know. Marusya does not even realize that their meeting is fraught with mortal danger.
