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.

Vinnie hesitantly goes back to work for the OCB under the promise they will help find Pete's killer, but Daryl is more interested in getting his star agent to work on a ""real"" assignment. Ritchie digs himself in deeper with the Pilgrims of Promise when he uses Vinnie's car to help rob an armored car. Depressed over Pete's death, Vinnie turns to Angie for consolation, but they both agree they don't want to risk their special friendship by becoming lovers. Vinnie talks Daryl into giving him weapons to sell to the Pilgrims, then he throws the bust when he sees they have Ritchie with them. (source: http://www.plasticcow.com/wiseguy)

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.

Knox Pooley realizes Calvin is insane and kicks him out, causing Calvin to go off the deep end and take a famous black leader hostage. Richie becomes disenchanted when he realizes Pooley was only in it for the money. Paul Beckstead takes over as director of OCB when Daryl cracks under the pressure and is dismissed for making obscene phone calls. (source: http://www.plasticcow.com/wiseguy)
