Wiseguy

A psychopathic murderer posing as Sonny's nephew double-crosses Sonny and holds Vinnie's girlfriend Gina hostage.

Vinnie nearly blows his cover when he becomes obsessed with finding out who killed his cousin, causing Frank to threaten him with dismissal. Frank desperately wants Vinnie to concentrate on nailing the Zaratzos, who are trying to arrange a drug smuggling deal with Sonny, because they killed one of Frank's agents.

After several deals go sour, Sonny starts suspecting Vinnie may be a plant. Frank orders Vinnie to drop the case when he finds out the local police have an informer in Sonny's operations. Sid has Frank picked up and tortured, but Vinnie and undercover cop Karen Malloy rescue him. Karen's disappearance points the finger at Sid as the leak.

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.

Sonny’s impending marriage to a syndicate boss’ daughter begins a supposedly businesslike realignment of “families,” but Vinnie learns that the wedding is a pretext for a bloody gang war.

An outraged Sonny Steelgrave accuses Vinnie of betraying him to his arch-rival, then realizes the devastating truth — that his paisan is an undercover Federal agent.

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.

Vinnie’s assignment to check out a contract killer leads him into a huge global contraband syndicate — an operation that far exceeds the scope of the Steelgrave family — overlorded by brother and sister Mel and Susan Profitt.

Vinnie, now a bodyguard for the Profitts, gets his first trial by fire when Mel Profitt, the brilliant but paranoid overlord of an international crime empire, disrupts the wedding of an associate, who retaliates by kidnapping Susan.

Vinnie tells Mel Profitt he is leaving to go home to New Jersey, but Mel offers him the biggest cocaine distribution network in the country — a plum that Vinnie feels is too juicy for any undercover cop to turn down.

When some of his munitions contacts begin drying up, Mel decides to blackmail a French Deputy Minister of Defense into supplying him with the weapons he needs.

Hiding out in Vancouver after the fall of the Steelgrave empire, Aldo Baglia sees a photo of Vinnie in the paper and decides to even the score, sending Vinnie into a coma from two serious gunshot wounds. Roger, using his CIA contact, tracks down Aldo.

After his munitions operation starts falling apart, Mel orders Vinnie to set up a meet with the mob to use his immense cocaine trade to regain financial power.

After rejecting an offer to finance a coup d'etat in the Caribbean, Mel Profitt becomes obsessed with a supposed voodoo death curse, and Vinnie, horrified, can only watch as Mel’s personality begins to disintegrate.

After Susan is arrested for Mel’s murder, Vinnie refuses McPike’s order to pull out of the Profitt case, because Susan, who has seemingly lost her grip on reality, has told him she is pregnant with his child.

With Mel and Susan Profitt undone, McPike begins dismantling their empire, but Vinnie demands to stay on the case to get to the bottom of Roger Lococco’s ties to a rogue CIA operation to stage a Caribbean coup d’etat.

Roger Lococco in effect signs his own death warrant by testifying to a Senate committee about a cabal within the U.S. intelligence community, but to back him up he needs Vinnie to testify as an O.C.B. operative — testimony that would end Vinnie’s career as an undercover agent.
