In the cyberpunk megalopolis named Zethropolis, the only one of its kind on the Dusk Frontier planet, two unlikely allies team up to solve a series of crimes: Betsy, an independant agent-turned-detective, tries to find the mastermind behind a public shootout, and Rachelle, a drug mule who has been dragged into a conspiracy against her will. Constantly having their way blocked by thugs, corruption and treason, their meddling puts a target on their back.

In a world that would see them fail, with enemies barring their way at every turn, can the two women succeed in their task? Or will the city win again, making two additional victims who will be forgotten like a pair of grain of sand in a desert?
