This has never happened before in the private practice of Polina Kazakova, whom everyone in the city knows as Miss Robin Hood. Her dear and beloved grandfather Aristarchus is accused of a cruel crime - incitement to suicide. Polina’s former classmate Anton Yartsev believes that it is Aristarkh Vladilenovich who has something to do with the death of his fiancee’s father. Ivan Ivanovich Bulatov hanged himself in his office, leaving a crumpled piece of paper with unfinished text: “I ask you to blame Arist for my death...” Many decided: we are talking about Polina’s grandfather. For the first time, Miss Robin Hood doesn't know what to do. Why not take revenge on your only relative?
