For centuries, Boston has been run by tough neighborhood crews that are in a constant battle for ultimate control and power.  In this ever-changing “street” landscape, these crews are the law, the keepers of an old world way of life. They run Boston's underworld with an iron fist; taking bets, offering loans, moving merchandise, solving problems and keeping the peace. For the first time ever, cameras are allowed unprecedented access onto the front lines of the never-ending turf wars between the Southie, Roslindale and Dorchester crews.
