This was the pilot for the hit series. Ken Wahl stars as Vinnie Terranova, a Justice Department agent reassigned to the Organized Crime Bureau (OCB) as a "wiseguy", a specially trained deep undercover agent. To help support his cover, Vinnie has just finished serving 18 months in a New Jersey prison. Vinnie is frustrated that he can't tell his mother that he is a government agent and not the criminal that he is now perceived to be. He wants out of the assignment, but after a friend is killed while investigating the Steelgrave crime family, Vinnie decides to go after ...
When Vinnie's young cousin, a boxer, is found dead of an apparent drug overdose, Vinnie jeopardizes his cover by going to "legals" -- the coroner, the homicide cops -- to get them moving on what he knows was a murder.
After his mother is mugged in Brooklyn, an enraged Vinnie sets out to find the punk who did it, but when he visits his mother in the hospital, it breaks his heart that she still won't forgive him for his life of "crime."
Sonny's cruel punishment of a lounge singer who wants out of his contract triggers a cascade of events that leads to Vinnie's being photographed with McPike -- a photo that is to be delivered to Sonny.
In the aftermath of the Steelgrave case, Vinnie tries to vindicate himself of his lingering feelings of betrayal and disloyalty by risking his life to save an old friend from the Brooklyn neighborhood who has a contract out on him.
