It's a doc about toxic exposure—sounds like standard activist cinema—but Cohen's refusal to resolve the rage, her willingness to let the mothers' testimony and the science sit in permanent friction, makes it genuinely unsettling in ways the genre usually avoids.
A formally restrained investigation that locates itself squarely in the lineage of concerned documentary inquiry, where the filmmaker's personal stake (her daughter's blood work) becomes method rather than melodrama; the architecture here is deliberate, each interview and test result placed with curatorial precision.
Cohen's decision to intercut her daughter's medical results with community health clusters could've been clumsy, but instead the quiet juxtaposition—letting data speak alongside lived experience—becomes the film's entire nervous system, turning a 52-minute investigation into something that feels both intimate and epidemiological.
