As the inquiry into the killing of a former bookie who became a mob informant unfolds, it uncovers a troubling twist in organized crime: legitimate business owners are secretly working as contract killers in a struggle for dominance within the mob. The situation escalates when the Federal authorities attempt to void the plea deal related to the case, infuriating McCoy and resulting in the deaths of two more individuals.
