Attack 13

The film opens with an extended prologue set in a dense Thai forest, where a shaman performs an ancient ritual involving live insects, reptiles, and binding incantations. This sequence establishes the supernatural framework that will later dominate the narrative, though its connection to the main story remains opaque until the third act. The action then shifts to present-day Bangkok, where Jinhandra transfers into a prestigious high school known for its volleyball program. She quickly identifies the toxic social structure maintained by Bussaba, who operates with the assistance of several lieutenants and the tacit approval of cowed faculty. Early scenes catalog Bussaba's cruelty in granular detail: forcing a classmate to clean dog feces from her shoe with bare hands, orchestrating a locker room water torture session, extorting money from vulnerable students, and publicly humiliating anyone who challenges her authority. Jinhandra's refusal to participate in this system makes her an immediate target. She befriends several of Bussaba's previous victims, including a quiet student named Ploy who bears psychological scars from years of abuse, and Toey, whose defiance once earned her particularly savage punishment. The group begins documenting Bussaba's behavior, collecting evidence through smartphone videos and text message screenshots, planning to present their case to school administrators. Bussaba discovers this conspiracy and responds with escalating violence, culminating in a confrontation during volleyball practice where she attempts to injure Jinhandra with a deliberately dangerous play. The altercation spills into the gymnasium after practice hours, where the exact sequence of events becomes contested. What's certain is that Bussaba ends up hanging from a volleyball net support beam, dead by apparent suicide. The discovery traumatizes the school, and Jinhandra becomes the subject of intense scrutiny, with some accusing her of driving Bussaba to suicide through retaliation. The supernatural element intrudes during Bussaba's funeral when her body mysteriously disappears from the temple. Shortly after, Ploy experiences the first attack: Bussaba's ghost appears in her dorm room, manifesting with spectral fury and gouging out one of her eyes before vanishing. The assault leaves Ploy hospitalized and terrified, and establishes the revenant's modus operandi. Bussaba's spirit retains her sadistic personality but now possesses superhuman strength and the ability to appear and disappear at will. She begins systematically targeting everyone involved in the gymnasium incident, attacking them in various locations with inventive brutality. One victim has their face repeatedly smashed into a bathroom mirror until the glass shards embed in their skull. Another is trapped in a locked car as Bussaba's ghost manifests in the back seat, strangling them while their friends watch helplessly from outside. Jinhandra researches shamanic practices and discovers that someone must have deliberately resurrected Bussaba using dark magic, binding her spirit to the mortal plane and directing her vengeance. The investigation leads to Bussaba's mother, a wealthy woman consumed by grief who paid a shaman to bring her daughter back, not understanding the consequences. The shaman, the same figure from the opening sequence, reveals that Bussaba's spirit is bound to the location of her death and to personal objects she treasured in life. The only way to banish her is to destroy these anchors and perform a counter-ritual. This quest takes Jinhandra and her remaining friends to Bussaba's childhood home, where they search for the objects while being stalked by the increasingly violent ghost. The third act complications begin when Jinhandra discovers evidence that complicates the simple victim-perpetrator narrative. Bussaba's personal effects include a diary revealing that she herself was once brutally bullied by older students, suffering abuse that drove her to a suicide attempt years earlier. Her reign of terror began as a defensive mechanism, a determination never to be vulnerable again. Additionally, text messages on Bussaba's recovered phone suggest that several students, including some in Jinhandra's group, engaged in their own forms of cruelty, spreading vicious rumors and creating fake social media profiles to mock Bussaba. The revelation fractures the group as members turn on each other, questioning who actually deserves protection from the ghost's wrath. During the climactic confrontation in the school gymnasium where Bussaba died, the remaining survivors attempt the banishment ritual while defending themselves from supernatural assault. Toey is killed when Bussaba's ghost impales her on a broken volleyball pole. The ritual requires someone to assume responsibility for the death, to acknowledge their role in the cycle of violence. Jinhandra ultimately confesses that during the gymnasium confrontation, she and several others did physically restrain Bussaba, and in the chaos, they may have inadvertently contributed to her death, leaving her suspended from the net rather than rendering aid. This admission satisfies some requirement of the ritual, and Bussaba's spirit begins to dissipate. However, in a final twist, Bussaba's ghost manifests one last time to kill her own mother, punishing her for the resurrection that trapped her in this vengeful existence. The film concludes ambiguously. Jinhandra survives but carries visible psychological wounds. The school implements new anti-bullying protocols, though the film suggests these measures are performative rather than substantive. In the final scene, a new student transfers into the school, and the camera reveals that other power hierarchies have already begun forming, implying the cycle continues. A post-credits sequence shows the shaman from the opening performing another ritual for a different client, suggesting his services remain in demand.
