Billy Chase could be killed at any moment. He is arguably the finest undercover cop fighting drugs. His record speaks for itself: He's put away many big-time dealers and even infiltrated the Gambino crime family. They want him dead, and if the drug gangs don't get him, his fellow law enforcement officers may. Billy Chase is black and has been mistaken for the very criminal element that he's after. Billy Chase is on the run. The hunter has literally become the hunted as he has risen to the top of the drug world's Most Wanted List. Death threats are common. Bullets have ripped apart the front of his house. The brake lines to his ex-wife's car have been cut. The already perilous job of maneuvering in plain clothes takes on one more intense layer when the officer is black or Hispanic, and is more apt to be mistaken for a criminal. Today Chase is a marked man. Death threats and violence have come in rapid-fire succession. He's gotten word through federal informants that it is just a matter of time before his enemies catch up with him. Not long ago he received a letter: "We know where you live...We know where your girlfriend lives. We're gonna kill her first, then you're next." The letter end, "U Pig." Billy Chase is a cop who knows what it's like for the hunter to become the hunted. His story transcends law enforcement. Its essence is distilled in a strong social message about what it means to be one man - alone, black, and undercover - who refused to give up the streets to criminals.
