Thundergod is a narrative experimental film set in a make-believe mountain village isolated from the outside world by frequent lightning strikes. One day, a young woman named Aoi appears in the village with dreams of dancing at an exclusive underground club open only to lightning strike survivors. Aoi wanders the village in a desperate daze, torn between life and death. The villagers she meets are split between those who live in fear of lightning strikes, and others who look to lightning as a harbinger of good fortune.
