A woman's daily commute takes an abrupt turn when she's dropped off in a grotesque shantytown in Edge of the Known Bus Line. The townsfolk live in huts and tents scavenged from broken trinkets. They eat dead rats and human flesh. They've developed cult-like religions about miracle bus routes that will someday set them free. The narrator searches for a way out of this surreal hellscape while dredging up a few nightmares of her own.
