Iberia Parish’s Sheriff Detective Dave Robicheaux is investigating the murder of a young woman, and has a chance encounter with Hollywood stars Elrod Sykes and his girlfriend Kelly Drummond. They are in the small town to make a Civil War film.
Due to Elrod’s erratic driving, Dave determines that the actor is driving drunk, and decides to arrest him. Objecting to being sent to jail, Elrod tells Dave of a decayed corpse that Kelly and he had found in the swamp. Dave goes to investigate, while remembering a murder he had witnessed as a teenager, where a chained prisoner was shot in the swamp and disappeared into the bog.
The discovery is soon tied to several murders in that area that had occurred recently, mostly to young runaways and prostitutes. The clues seem to point to Julie “Baby Feet” Balboni, whose ties with the mafia had caused Dave and him to drift apart and become enemies. Balboni denies knowing the prostitute whose murder is being investigated.
With little to go on, Dave visits the film site and meets the producer, Michael Goldman, who states that while Baby Feet is helping to fund the film, he is not a co-producer as he had said.
Meanwhile, Dave’s home life is disrupted by Elrod and Kelly, who begin turning up regularly, almost every time with Elrod being drunk. This prompts Dave to take pity on him, as he, too, is a struggling alcoholic. Dave’s daughter, Alafair looks up to movie star Elrod, but wife Bootsie has concerns.
The discovery of a second body prompts the FBI to become involved in the case. Dave is partnered with agent Rosie Gomez. Dave attends a birthday party for Goldman, and though drinking Dr Pepper, becomes terribly uncoordinated during his drive home, and crashes his pickup truck, sending him off in a daze to the forest.
On the last occasion that Dave sees General Hood, the general and a few of his Confederate comrades are breaking camp and preparing to leave. A story from an alleged pimp corroborates a suspect, Murphy Doucet, who with his partner Twinkie Lemoyne is responsible for the murder of DeWitt Prejean, the skeleton found in the swamp.
Months later, Dave, who had stopped seeing visions of General Hood after the case was solved, determines that he was a figment of his imagination, a lingering spirit to help him through the most difficult case of his life. As the story ends, Alafair is looking through a book on the Civil War when she comes across a photograph of General Hood and his soldiers.
