After making films like samurai epics 13 Assassins and Hara Kiri and the children’s film Ninja Kids!, Takashi Miike returns to familiar horror territory with Lesson of the Evil, based on a best-selling horror novel. Clean-cut pop star Hideaki Ito plays Mr. Hasumi, a young, popular, good-looking teacher at an elite high school. While he’s beloved by his students and popular with pretty much everyone, Mr. Hasumi has a dark secret past and homicidal urges that can’t be contained.
