Vinnie is released from prison where he has been for two years to establish his cover. He meets his boss, Frank McPike and gets to see his coach and mentor, Jerry Greco. Greco is killed and Vinnie demands to be put in to finish the investigation. He uses his ingenuity to get a foothold in the Steelgrave crime family, but it will take a while to finish this job.

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.”

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.

After resigning, Vinnie returns to his old neighborhood to try and get some peace after his life undercover, but is distressed to find white supremists are stirring up trouble. Daryl Elias is promoted to OCB director and orders Frank to either bring Vinnie back to work, or in for debriefing. After a synagogue is trashed, Pete speaks out against the white supremists and is then murdered in a hit and run accident, making Vinnie rejoin the OCB to find his killer.

Unbeknownst to Vinnie, his car was used in the robbery where an off-duty cop was killed, leading to his arrest and brutalization at the hands of the NYPD. Frank bails him out, then reluctantly lets Vinnie continue his pursuit of Knox Pooley. Vinnie tells Ritchie he's a cop and asks him to help him gather evidence against the Pilgrims. Vinnie goes to a Pilgrim rally and stumbles across the truck that was used to kill Pete, then agrees to a meet with Stan in the hopes of tying Pooley to it, leading to Stan and Ritchie's arrests.

Concerned that Vinnie is addicted to the pain pills he's been taking for his leg, Frank calls in Paul Beckstead, who orders Vinnie to undergo a routine physical exam. At the hospital, Daryl Elias is undergoing therapy and, holding Vinnie responsible for his downfall, he accesses Vinnie's file and orders that he be held for psychiatric evaluation. When Vinnie resists, he is sedated and locked up against his will. While in his drug-induced twilight zone, Vinnie's worst nightmare comes to life in the form of Sonny Steelgrave, who blames Vinnie for his death. (source: http://www.plasticcow.com/wiseguy)
