In the sweltering heat of Louisiana bayou country, veteran detective Dave Robicheaux, portrayed by Tommy Lee Jones, finds himself haunted by both the past and present when he investigates the murder of a young African American woman. As Robicheaux delves deeper into the case, he discovers unsettling connections to a serial killer from decades earlier, a shadowy figure he has never been able to forget. The investigation forces him to confront not only the brutal realities of modern crime but also the ghosts of the Civil War era that still linger in the region's collective memory. With a stellar supporting cast including John Goodman as a flamboyant mobster, Peter Sarsgaard as a suspicious movie star, and Mary Steenburgen as Robicheaux's steadfast wife, the film weaves a dense tapestry of Southern gothic intrigue. Directed by Bertrand Tavernier, this atmospheric drama blends police procedural elements with philosophical reflections on justice, memory, and the inescapable weight of history. As the bodies pile up and the clues grow stranger, Robicheaux must navigate a treacherous path through corruption, violence, and his own demons, all while the electric mist of the Louisiana night threatens to swallow the truth whole.
