In a post-Soviet oilfield, death and mutation spread among the people and animals. A veterinarian investigating the cause of livestock stillbirths is met with resistance from the state-run oil refinery. As she delves deeper, she uncovers disturbing evidence of contamination and is warned to stop her investigation for her own safety. But when her own daughter falls ill, she must weigh the risk of uncovering the truth against her daughter's well-being. A mysterious man offers a choice: abandon her investigation and erase all evidence, or risk losing her daughter forever. The fate of the town rests on her decision, as horrors lurk around every corner in the shadow of the oilfield. Will she uncover the truth, or succumb to the forces of darkness?
