At the Croton Filtration Plant in Bronx, NY, Walking Boss Morgan Curran and his gang of Sandhogs finish prepping the mole for it’s third and final tunnel. With work picking up again Morgan rehires Elom, Mikey Bones and Romo, returning his old gang to full strength. With Morgan thinking forward to the next job, he needs his gang to begin this final segment without incident, to ensure their future prospects. Over at the East Side Access site in Queens, Sandhog foreman Tom Kelly oversees a series of precise blasts. But a nagging shoulder injury sends him to the doctor where he is told to stay off of ladders and away from heavy equipment. Ignoring the doctor’s advice, Tommy returns to the job the next day to build a protective bulkhead, helping to secure to tunnel against the blast. He pays for his efforts with a dislocated shoulder, but his hard work saves the day for the hogs. Back at Croton, the mole gang encounters a string of bad luck, and mining production falls below average. Morgan, concerned that this will tarnish the reputation of his gang, pushes his crew to step in up - or else.
