A high-school teacher is arrested for having sexual relations with a minor. Young Hiromi finds herself in the eye of the storm when she is suspected of featuring in her teacher’s leaked sex video and her innocence is questioned by everyone around her.

Kyoko was born and raised in Mishima City, a place built on the lava flow of Mt. Fuji. As her family's shoe store closes, she feels adrift, losing her sense of belonging. Her older sister Asuka, who worries about Kyoko, also harbors a different kind of anxiety. In the background, the traditional festival music "shagiri" resonates throughout the town.
