The movie "The Lemmings of Hakoniwa" is a comprehensive drama composed of four independent stories, deeply depicting the darkness and fear experienced by young people in the SNS world. Each story reveals different perspectives on the psychological states and contradictions of young people trapped in social media networks.

In the first episode, the character "Impure Nai" played by Ai Mikami is facing excessive desire for recognition. She longs for more attention and praise on SNS, but gradually falls into self-lost and mental distress.

In the second episode "Lynching Club", Okayama Tianyin plays the leading role, telling about the out-of-control sense of justice on SNS. In cyberspace, in the name of morality, some people spontaneously form so-called "lynching clubs" to publicly criticize and humiliate those who are considered "bad guys", causing confusion in moral boundaries.

The third episode, "Detective S," starring Kenta Suga, portrays the fear of cyberstalking that identifies personally identifiable information. In the digital age, where our personal information is virtually invisible, this pervasive surveillance is unsettling and frightening for young people.

In the last episode "Not Famous", Isomura plays a young man who takes extreme actions in order to increase the number of fans. In order to become more famous on SNS, he did not hesitate to attract attention in a dangerous way, and this behavior also exposed his vanity and anxiety.

Through these four stories, the film "The Lemmings of Hakoniwa" deeply explores the psychology and behavior of people in the SNS world.
