Kingpin: Whitey Bulger

In the 1970s, the Boston underworld is in chaos. Dozens of Irish neighborhood gangs have spent decades brawling over turf, creating a power vacuum. But one Machiavellian foot soldier will scheme and kill his way through the ranks to become the most famous gangster in Boston history, leaving a unified Boston Irish Mob and the longest manhunt in U.S. history in his wake.
