Secrets fester, and danger lurks in the shadowed depths of Louisiana's bayous. Private investigator Wyatt Thomas is summoned to the sleepy town of Pinebridge by notorious mob boss Frankie Castellano. His mission is to find Frankie's missing half-sister, Bella Donna Castellano, who vanished from the Louisiana Mental Hospital under suspicious circumstances.
On his first night in town, Wyatt stumbles upon a gruesome murder, drawing him into a web of corruption and cruelty. Partnering with Maya Henstooth, a tenacious Rapides Parish homicide detective with a mysterious past, Wyatt uncovers the dark truths behind the hospital's walls. Patients are subjected to horrific abuse, illegal experiments, and disappearances orchestrated by the sinister Dr. Felix-a man with a hidden identity and chilling connection to Wyatt's world. As Wyatt and Maya delve deeper, they uncover a horrifying plot. Dr. Felix and his twin brother, Axel Devereaux, plan a grotesque banquet at their mansion, intending to silence Wyatt and Frankie forever in front of their cult of red-cowl-clad followers. With time running out, Maya must embrace her newfound powers to ignite a battle against unspeakable evil.
