Tee Yod

It is 1972 in a remote farming village in Kanchanaburi Province, western Thailand. A girl named Nart has just died after a prolonged, unexplained illness, and the village carries its grief alongside a quieter, unspoken fear. A family of eight — two parents, three sons named Yak, Yos, and Yod, and three daughters named Yad, Yam, and Yee — are already living with the knowledge that something in the area is not right.

Three of the sisters encounter a figure in a black dress standing beneath a tree near the house. Not long after, Yam begins to change. She enters trances. She leaves the house at odd hours. Her speech and behavior shift in ways that resist ordinary explanation — sometimes she seems entirely present, and sometimes she seems like someone else entirely. The family watches it happen and doesn't yet know what to call it.

An old woman named Chauy appears and attacks Yam, extracting one of her teeth. Yak, the eldest son, investigates and learns the truth from his friend Sarge: Chauy is a practitioner of dark folk magic who has been preparing Yam to become the new host for an evil spirit that has been feeding on the village. Before Chauy can complete the ritual, she kills herself, leaving the spirit already partially anchored in Yam.

The family calls on a priest named Puth. He identifies the problem and prescribes a course of action: cut down the bamboo tree near the house. Inside it they find human organs — a heart that is still beating among them. They burn everything. The act breaks the spirit's anchor but does not release Yam, who is still possessed, still deteriorating, and now bleeding time.

They load Yam into a truck and drive through the night toward the nearest hospital. The journey becomes a gauntlet. The possessed Yam whispers constantly from the back — a sound that induces a creeping drowsiness in anyone who hears it, a weight behind the eyes that erodes alertness. Hallucinations break out among the passengers. Yak loses control of the wheel. The truck crashes. Puth is killed. In the chaos following the wreck, the possessed Yam shoots one of their companions before she is stabbed and the group pushes on, fractured and diminished.
