In 1987, in a village at the foot of Mount Elephant Island in Kedah, on the border between Malaysia and Thailand, villager Achang is a devout believer in the folk god Dato Gong, but his wife Ayan disagrees. One day, Achang drove away a snake in front of the shrine and accidentally broke the wall of the Siamese neighbor's house. Two weeks later, Achang suddenly fainted on the ridge of the field, vomiting blood and rusty nails. The villagers knew about it and each had their own story. Ayan didn't believe it at all and decided to look for a prescription for her husband. Three months later, Achang's illness did not heal for a long time. Ayan had no choice but to go to the cave to worship the mountain god of Elephant Island. At this time, a woman appeared in the cave and told her the legend of the Langya repair era. In an instant, Ayan seemed to be in the fusion and opposition of the border, and was deeply trapped in panic and the unknown. This film outlines a new look of Eastern mysticism with exquisite audio-visual language and superb scene arrangement.
