Miriam (Madeleine Sims-Fewer) is a woman treading water in an unhappy marriage who hopes to find solace in a weekend reunion with her estranged younger sister, Greta (Anna Maguire), at a secluded cottage estate. Along with their respective husbands, Miriam’s brooding partner Caleb (Obi Abili) and Greta’s affable Dylan (Jesse LaVercombe), they find themselves navigating a minefield of one another’s sensitivies and histories, culminating in a traumatic series of betrayals — the root of which is a deeply upsetting act of sexual violence.
