In a strange world, a solitary girl awakens to find herself without familiar company. As she explores her surroundings, she encounters a girl who is her mirror image down to the last detail except for their names: 328 and 329. Although they find running water, there is no food to be had. Their quest for sustenance leads them to discover a raft that could help them depart from this enigmatic realm, but it's clear that only one person can ride it. The incessant buzzing of winged insects, the gnawing hunger pangs, and their mutual longing to escape test their sanity to the extreme, and one of them will inevitably reach their breaking point.
