After a botched undercover operation, ex-NYPD officer Marshall Grade is living in witness protection in Santa Fe, New Mexico. Marshall's instructions are to keep a low profile: the mob wants him dead, and a contract killer known as the Dallas Man has been hired to track him down. Racked with guilt over wrongs committed during his undercover work, and seeking atonement, Marshall investigates the disappearance of a local woman named Alyce Ray. Members of a drug ring seem to hold clues to Ray's whereabouts, but hunting traffickers is no quiet task. Word of Marshall's efforts spreads, and soon the worst elements of his former life, including the Dallas Man, are coming for him.
