The indomitable Lucas Davenport (now happily married, a contented father and bored out of his mind) is slogging through the northern tundra of Broderick, Minnesota, to inspect the naked dangling corpses of a white woman and black man ("They were frozen. Like Popsicles.") that have shocked the locals as well as Minnesota's governor with the ugly specter of a lynching.
Davenport, now more or less a free agent for the state's Bureau of Criminal Apprehension ("I kick people's asses"), is unleashed by the governor, giving Davenport and his scruffy sidekick, Del Capslock, a chance to escape their square city lives and catch the villain(s) while staving off the media vultures.
The original crime (rendered in a truly horrific opening sequence) is merely the gateway to a deeper, more insidious criminal enterprise, this one an international labyrinth of stolen cars, drugs, gambling and kidnapping. Some truly vicious familial machinations in the small town contrast well with Davenport's staid and stable home life.
Another pleasant surprise is the precocious Letty West, whose awakening teenage sensibilities make an impression on Davenport.
