Walker Dett is a hired gun, known for using the most extreme measures to accomplish his missions. Royal Beaumont is the "hillbilly boss" who turned Locke City from a dying town into a thriving vice capital. But organized crime outsiders are moving in on Beaumont's turf, so he reaches out for Dett in a high-risk move to maintain his power at all costs. Add a rival Irish political machine, a deeply entrenched neo-Nazi "party", the nascent black power movement, turf-disputing juvenile gangs, a muck-raking journalist who doubles as a blackmailer, the FBI--a covert observer and occasional participant which may itself be under surveillance-- and Locke City is about as stable as a nitroglycerin truck stalled on the railroad tracks.
