Based on the novel The Unbelieved by Vikki Petraitis. Dustfall is described as a propulsive, atmospheric Tropic Noir that follows a detective whose deep sense of justice is challenged by a world where victims are doubted, predators hide in plain sight, and the legal system too often falls short. When seasoned detective Tig (Torv), returning to her hometown of North Gap after years in the city, uncovers a string of drink spiking assaults, the case is turned on its head when one of the main suspects is found murdered.

Set against the backdrop of modern-day Sydney, this heist-style thriller involves four politicised women from varying backgrounds, who conspire to sabotage the research programme of a multi-national firm, Utero, which is engaged in reproductive engineering. One of the women loses her diary which contains information and diagrams about the raid only a few days to count down. Will the diary fall into the wrong hands leading to the detection of the women before they have a chance to complete their mission? As the tension mounts, so the wider context of the women's lives as mothers, lovers and providers is also shown under strain indicating the many other considerations women have to take into account when embarking on any form of public activity.
