Suffering from insomnia, wise-cracking tough guy Thomas O'Shea goes for a late-night stroll through the peaceful streets of Rockbluff, Iowa. Pausing downtown on the bridge spanning the Whitetail River, something catches his eye. He scrambles down to the riverbank, where he discovers the nude body of a young girl with bullet holes in the back of her head. When the coroner's report lists the cause of death as "drowning," Thomas confronts him but is met with hostility. Then, mysteriously, the coroner and his wife disappear, along with the body of the dead girl. Thomas teams up with a buddy from his Navy SEAL days and a local Ojibwa bar owner named Lunatic in order to bring justice to the girl…and they walk straight into the world of organized crime.
