Russia's drug crisis unfolds in Novokuznetsk, a Siberian city near the Kazakhstan border, where a homemade opioid called krokodil has taken hold among addicts who can no longer afford heroin. The film follows users and their families as they describe cooking the drug from codeine tablets and household chemicals, a process that leaves flesh scaled and rotting at the injection site, giving the drug its name. Interviews with addicts, local doctors, and outreach workers lay out why krokodil spread so fast: it is cheaper than heroin and easier to make than to import. The footage does not look away from the physical damage, including open wounds and amputations, and pairs it with blunt testimony about how quickly the drug kills, often within a year or two of first use. Set against Russia's broader status as the world's largest heroin consumer, the film treats Novokuznetsk as a case study in what happens when a black market drug supply collapses and users turn to whatever is left.
