With Nucky’s head gangster status being challenged by the smooth-talking and confident Harlem King Doctor Narcisse (Jeffrey Wright), his operation is going to have to rise to the occasion or risk seeing their boss toppled. But will they have what it takes to go up against Doctor Narcisse’s men? Watch the trailer below and let us know what you think in the comments.
