Connor and Murphy resolve to rid Boston of evil men. Connor learns of a meeting of Russian syndicate bosses at a hotel. Having equipped themselves with weaponry from a local underground gun dealer, the brothers quickly kill all nine Russian mobsters, while Rocco, a friend of the brothers and mob errand boy for local mafia boss Giuseppe "Papa Joe" Yakavetta, is sent in on an independent hit as an unknowing throwaway. The next day, Rocco learns that he was betrayed by Papa Joe, the hit amounting to an attempt to have Rocco killed by the nine Russian mobsters as he was sent in with only a six-shot revolver. As a result, Rocco commits himself to help Connor and Murphy. That night, the MacManus brothers and Rocco hunt down an underboss of the Yakavetta crime family, Vincenzo Lapazzi, and kill him.
