Sinopsis Delusion
When her father's worsening dementia makes him a prime suspect in a murder case, a small-town schoolteacher races to uncover the truth amid dark rumors. 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, 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, a provincial high school teacher, to stand up and fight against the town’s rumour 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. (Source: Netflix)
