Sensor (2021)

A woman walks alone at the foot of Mount Sengoku. A man appears, saying he's been waiting for her, and invites her to a nearby village. Surprisingly, the village is covered in hairlike volcanic glass fibers, and all of it shines a bright gold. At night, when the villagers perform their custom of gazing up at the starry sky, countless unidentified flying objects come raining down on them -- the opening act for the terror about to occur!
