This 11x60 series follows the lives and efforts of Local 147, New York City's Sandhogs. These are the city's infamous tunnel workers, men who daily blast through some of the planet's hardest rock, directly under some of it's most expensive real estate. This is a supremely dangerous job done by the best in the business. Sandhogs work 24 hours a day right below millions of unsuspecting New Yorkers on out-of-sight projects that are as massive and complicated as they are beautiful and fascinating.
