Monster (2023) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Monster (2023), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

Saori Mugino, a devoted single mother, faces a troubling situation as she raises her fifth-grade son, Minato. His behavior takes a bizarre turn when he starts cutting his own hair and returns home with only one shoe. The situation escalates when one night, Minato goes missing, prompting Saori to frantically search for him. After making several calls, she ultimately finds him in an abandoned train tunnel.

Suspecting that Minato’s teacher, Mr. Hori, might be abusing him, Saori approaches the school, only to be met with indifference from the faculty. The apathy peaks when Mr. Hori offers a surface-level apology that feels insincere. Upon confronting him directly, she learns that Minato may be bullying another student, Yori. This revelation leads her to visit Yori’s home, where she discovers that he, despite his own peculiarities, is both fond of and protective towards Minato.

In a shocking twist, Mr. Hori is dismissed from his teaching position but unexpectedly reappears shortly after. In a moment of tension, Minato falls down a flight of stairs while trying to evade him. Amidst a brewing storm, Hori visits Saori’s home, only to realize that Minato has vanished yet again.

The narrative delves into Hori’s perspective, revealing his suspicions about Minato’s disruptive behavior, including troubling actions like throwing classmates’ belongings and allegedly locking Yori in a bathroom stall. Hori’s visit to Yori’s home uncovers a challenging truth; Yori’s father, Kiyotaka, struggles with alcoholism and delusion. As Saori presses for answers regarding Minato’s welfare, Hori faces mounting pressure from the school staff to remain silent for the institution’s sake, leading to his resignation.

After facing media backlash and being abandoned by his girlfriend, Hori grapples with despair, considering a drastic step from the school rooftop after Minato’s accident. In a moment of revelation during the storm, he discovers a typo in Yori’s old homework that seems to hint at Minato’s name. Realizing the connection, Hori rushes to apologize to Saori, only to find out Minato is still missing. Together, they return to the train tunnel, where they uncover an abandoned railcar partially submerged in mud, but tragically only find Minato’s discarded poncho inside.

The story circles back to Minato’s perspective; he reflects on his bond with Yori, who faces bullying for his socially awkward demeanor. The two boys become inseparable as they find solace in their friendship, even as Minato grapples with burgeoning romantic feelings and his sense of inadequacy. One fateful night, they reach a breaking point after a tense encounter with Yori’s father. In a turn of events during the storm, Minato discovers Yori abandoned in a bathtub, and together they seek refuge in their secret hideout within the abandoned railcar. As the rain clears, they emerge renewed, joyfully running through a field, hinting at a new beginning.

Ending Explained – What Happens at the End of Monster?

Still wondering what the ending of Monster (2023) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.

In the end, Monster reveals that the true monsters are not external figures but often misunderstandings and misconceptions that distort our perceptions. Throughout the film, characters grapple with false accusations, rumors, and prejudice, which lead to tragic consequences. Hori is unfairly blamed for the injuries inflicted on Minato, while rumors about him and Saori damage her reputation and mental state. The school authorities, driven by their desire to protect the institution, inadvertently worsen the situation by rushing to judgments without proper investigation. Meanwhile, Minato and Yori’s friendship is kept secret because of societal pressures that equate closeness between boys with weakness or effeminacy, underscoring how fragile and distorted perceptions of masculinity can prevent genuine understanding and connection.

When we shift perspectives to Yori, it becomes clear that Minato and Yori’s bond was genuine and caring, built in secret because of fears of judgment. The film’s climax shows that the boys have found solace and happiness in their friendship, despite all the misunderstandings around them. The final scenes, filled with light and laughter, symbolize a renewal—a moment where the characters realize that their fears and prejudices were based on false monsters. In Kore-eda’s poetic style, the film closes on a note of innocence and hope, illustrating that compassion and truth can ultimately dispel the darkness created by misconceptions. The story ultimately suggests that true monsters—those born of misunderstandings—are what threaten our capacity for kindness and connection if left unchecked.

At the end of Monster, it becomes clear that the real monsters are not external figures but the misunderstandings and prejudices that distort how we see others. Throughout the film, characters fall victim to rumors, false accusations, and societal judgments that lead to tragic outcomes. Hori, the teacher, is unjustly blamed for the injuries and behavioral issues of Minato, while Saori’s reputation suffers due to unfounded rumors about her and her son. The school authorities, eager to protect their image, rush to judge Hori without thorough investigation, making the situation worse. Meanwhile, Minato and Yori’s friendship is kept secret because societal stereotypes associate closeness between boys with weakness or effeminacy, revealing how fragile and damaging perceptions of masculinity can be.

When the story shifts to Yori’s perspective, we learn that Minato and Yori’s bond was authentic and nurturing. The boys’ friendship, kept hidden out of fear of ridicule, is a symbol of genuine connection amid the chaos of misunderstanding. The final scenes depict the two boys happily playing together, unburdened by the fears that once haunted them—a moment of innocence and hope. Kore-eda’s poetic style emphasizes that these “monsters”—the falsehoods and prejudices—are ultimately illusions that can be dispelled through compassion and truth. The ending suggests that it is our own misconceptions that pose the greatest threat to kindness and human connection, but there is always room for redemption and understanding when we choose empathy over suspicion.

In the end, Monster shows us that the true monsters are not external threats but the misunderstandings, rumors, and prejudices that distort reality. The characters are caught in a web of false accusations—Hori is wrongly blamed for Minato’s injuries, Saori’s reputation is damaged by rumors, and the school’s rush to judgment only worsens the chaos. Minato and Yori’s friendship remains secret because of societal stereotypes that associate emotional closeness between boys with weakness, exposing how harmful stereotypes about masculinity can hinder genuine connection.

When the story is told from Yori’s perspective, it becomes evident that their friendship was sincere and caring, hidden out of fear rather than malice. In the final moments, the two boys, unburdened by their fears, run and laugh freely, symbolizing hope and innocence. Kore-eda’s subtle and poetic storytelling ends with a powerful reminder that the true monsters—the misunderstandings and prejudices—are illusions that can be overcome with empathy and understanding. Ultimately, the film suggests that kindness and truth are the best shields against the darkness created by false perceptions, leaving us with a message of hope that genuine human connection can triumph over ignorance.
