Deep within southside Virginia lies the Snakefoot --- a wild swampland that holds secrets, hides truths, and harbors the dead in murky waters that refuse to shine yet somehow glow. One morning, a pickup truck is found jammed into the mud, the driver’s door open amidst scattered bullets and bloodstains on the seat. The driver, Rainbo Boon, is nowhere to be found, but his tracks lead Deputy Sheriff Will Seems and his partner, Tania Jameson, into the swamp. During their investigation, Buck Tomlin, the grandson of the missing Rainbo, proves cooperative, at least at first. But when the boy’s whereabouts from the night of the accident don’t check out, Will and Tania must confront the troubling reality that the Snakefoot might hold more than just a runaway victim.

After a decade of exile precipitated by the tragic death of his mother, Will Seems returns home from Richmond to rural Southern Virginia, taking a job as deputy sheriff in a landscape given way to crime and defeat. His efforts to go about his life are wrecked when a mysterious, brutal homicide claims the life of an old friend, Tom Janders, forcing Will to face the true impetus for his return: not to honor his mother's memory, but to pay a debt to a Black friend who, in an act of selfless courage years ago, protected Will and suffered permanent disfigurement for it. Meanwhile, a man Will knows to be innocent is arrested for Tom's murder. Will must weigh his personal guilt against his public duty when the local Black community hires Bennico Watts, an unpredictable private detective from Richmond, to help him find the real killer.
