A vicious schoolyard bully terrorizes her classmates until one day, she's the one who ends up dead. But death is just the beginning. From Death Whisperer director Taweewat Wantha comes a savage twist on the revenge ghost story: here the bully becomes the vengeful spirit, exposing how violence breeds violence. Rising star Aheye (of K-pop-influenced girl group 4EVE) commands the screen alongside model-turned-actress Lilly in a film that's become a phenomenon among young Thai audiences, who've turned preview screenings into communal scream-fests. While recent Thai horror has leaned toward prestige period pieces (The Cursed Land) or franchise expansions (Death Whisperer 2), Attack 13 pulses with contemporary energy—a razor-sharp generational portrait wrapped in visceral terror. Horror that speaks directly to its moment.
