On the #7 Subway line extension project, Walking Boss Martin Hostetter and Foreman Ryan McGinty ready their gang for an important two weeks. They are preparing the final few blasts to complete the giant subterranean cavern.

But as they work, mechanical problems slow their progress, and frustration mounts. Over at the East Side Access site, the West Tunnel mole gang confronts one obstacle after another in their efforts to mine 25 feet a day.
