The Medium
A documentary crew follows Nim, a shaman in a rural Thai village who is the vessel for a benevolent local deity, Bayan. When her niece, Mink, begins to display erratic and disturbing behavior, the family believes she is the next in line to inherit the spirit of Bayan. However, as Mink’s condition violently deteriorates and her actions become increasingly demonic, it becomes clear she is possessed not by Bayan but by a multitude of malevolent spirits, likely linked to a curse on her father's family. After several failed attempts to help her, a desperate, large-scale exorcism is performed, which backfires catastrophically, descending into a bloody massacre as the overwhelming evil within Mink slaughters Nim, her family, and most of the film crew.
