The Medium

The movie starts with a group of Thai documentary team traveling to the northeast part of Thailand, Isan to document the daily life of a local medium, Nim, who is possessed by the spirit of Bayan, a local deity whom the villagers worship. Bayan is an ancestral God and has been possessing women in Nim's family for generations. The latest in the line of succession was Nim's cousin, Noi. However, Noi did not wish to be a medium and turned to Christianity. The spirit of Bayan moved onto Nim and has been with her ever since.
