Synopsis: Delusion plunges viewers into a chilling mystery set in the quiet district of Chiang Khan, Loei Province. A child's disappearance reawakens something the town has spent over a decade trying to forget and bury. As fear takes hold, the old legend of "Phii Pong" resurfaces, and as the town hunts for someone to blame, the suspicion settles on Narong (Nu-Surasak Chaiyaat), an elderly man whose worsening dementia makes him impossible to defend, and impossible to trust — even by his own family.
This forces his daughter, Wan (Natapohn Phornprapha), a provincial high school teacher, to stand up and fight against the town’s rumor and prove that her father is only a sick man who needs care, not the monster the town has decided he is. But every answer she uncovers only raises more questions, and the closer she gets to the truth, the less she recognizes the people closest to her, the ones she calls family. (Courtesy Netflix, 2026)
