S1·E17 A Made Guy

Cole interrupts a mob transaction between Jimmy and one of the prisoners, Trepp. Cole captures Trepp and escapes, but realizes that Zin and the mob are connected somehow. Despite Mel's reluctance and with Nestov's assistance, Cole takes on the face of an obscure 20's mobster and goes undercover, using his techno-gizmos to give himself a cover story with Tommy, the head mobster. Zin and Tommy's gang are rivals, with Zin taking over their territory. Despite Jimmy's suspicions and Vic's interference, Cole manages to find out that Zin is drilling 300' down in several buildings in the downtown area. Tommy and his gang end up in jail, leaving Cole with another piece of the puzzle.
