"In Atlanta, Kenny Bomar is a biochemist-turned-coffee-shop-owner in denial about his divorce and grieving his stillborn daughter. Chemicals killed their child, leaching from a type of plant the government is hiding in Black neighborhoods. Kenny's coping mechanisms are likewise chemical and becoming more baroque -- from daily injections of lethal snake venom to manufacturing designer drugs. As his grief turns corrosive, it taints every person he touches. Meanwhile, Black epidemiologists Retta and Ebonee are called to the scene when a mysterious black substance is found to have killed a high school girl. Investigating these "blackouts" sends the women down separate paths of blame and retribution as two seemingly disparate narratives converge in a cinematic conclusion"-- Provided by publisher.
