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.
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 Loccoco 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.
Knox Pooley's explosive appearance on an issue-oriented talk show ends in tragedy, and Vinnie and Richie join forces to link yet another brutal murder to the Pilgrims of Promise evangelist.
When Vinnie's mother falls in love with an organized crime boss, rekindling a romance that began in the old country, the O.C.B. asks Vinnie to intervene.
Vinnie goes undercover for the O.C.B. as a garment-center security consultant to keep the new wave of organized crime leadership from destroying a father-and-son business.
