OLD DEBTS ARE FINALLY PAID BY A MOB SNITCH -- When a former bookie is murdered in an apparent professional hit, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) search the victim's background for a possible suspect. However, when the victim turns out to be a mob informant who sent a local kingpin to jail for the past decade, the detectives sets their sights on a real-estate broker moonlighting as a killer-for-hire who is allegedly taking orders from the mob.
