It's 1987, and Detective Georgia Cooke is called in to investigate the massacre of four scientists who have been brutally murdered in inexplicable ways, with a lone survivor the obvious suspect. But as Georgia digs deeper, unravelling a complex case entangled in mania, ritual, and the occult, her obsessive quest for the truth spirals into a nightmare that will put her family, career, and sanity on the line. 

37 years later, a chilling new spree of murders will pull Georgia back into this nightmare as she confronts the terrifying possibility that the horrors at Parrish Station were never fully buried.
