Reese must protect Charlie Burton, a school teacher (Enrico Colantoni) who witnessed a Russian mobster shooting an Italian-American mob lieutenant in a Brighton Beach bodega. As Reese and Burton flee the Russians and the Five Families, they stumble into territory controlled by Bulgarian mobsters. Meanwhile, Carter searches for Burton to place him in protective police custody, and in doing so, draws closer to finding "Elias M." — believed to be the illegitimate son of an ageing mobster with a plan to unite the Five Families and reclaim the New York underworld from the Russians. Cut off from Finch as he tries to evade the Russians and the Bulgarians, Reese comes to realise that Charlie is Elias. Elias warns Reese to stay away or face unpleaseant consequences, leaving Reese feeling guilty that other people will suffer because he saved Elias' life.
