Attack 13

New student Jinhandra arrives at a Bangkok high school dominated by Bussaba, a vicious bully who terrorizes her classmates through physical violence, extortion, and calculated humiliation. The social hierarchy operates with brutal clarity: Bussaba commands absolute power, and resistance invites escalating punishment. Jinhandra, a talented volleyball player with an independent streak, refuses to submit to this regime, drawing Bussaba's focused malice. Other students who have suffered under Bussaba's rule gravitate toward Jinhandra, recognizing in her a potential ally or catalyst for change. The conflict intensifies through a series of confrontations that expose the institutional failure enabling Bussaba's reign, with teachers and administrators turning blind eyes to obvious abuse. The tension reaches a breaking point during a charged encounter in the school gymnasium, where circumstances converge to produce a shocking result: Bussaba is found hanging dead, an apparent suicide that devastates the school community. The tragedy seems to close one chapter of violence, but something far worse begins when Bussaba's corpse vanishes from the morgue and her spirit returns, animated by shamanic magic and driven by supernatural rage. What follows transforms the film from social drama into paranormal thriller, as Jinhandra and her friends face attacks from an enemy who can no longer be reasoned with or defeated through conventional means.
