Lesson in Murder

Masaya is a university student, but he attends a school that's not his ideal school. His days are generally gloomy. One day, he receives a letter from serial killer Haimura. He was convicted for nine murders and received the death penalty. Back when Haimura was committing his murders, he ran a bakery store. At that time, Masaya was a middle-school student and a customer at his bakery store. According to the letter, Haimura confesses to having committed eight murders, but he insists that he did not commit the last murder. Masaya begins to investigate the last murder case involving Haimura.

Directed by Kazuya Shiraishi, Lesson in Murder leans on a strong ensemble — Sadao Abe, Koshi Mizukami, Takanori Iwata — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about mystery titles of 2022.
