‘Boardwalk Empire’ Premiere Includes Klan, Cops, Treacherous Insiders

Nucky Thompson will face a barrage of threats to his enterprise starting Sept. 25

"Boardwalk Empire" will return Sept. 25 with an insurrection, an arrest, and a terrifying visit from the Ku Klux Klan, HBO announced Wednesday.

The season two premiere, titled "21," will find Nucky Thompson (Steve Buscemi), Atlantic City's man behind the curtain, contending with trouble in his inner circle.

Chalky White, meanwhile, suffers a life-threatening attack from the Klan, and Margaret Schroeder, Nucky's on-again off-again squeeze, contends with her son's disciplinary problems. It airs at 9 p.m.

In its statement about the premiere date, HBO also dropped some hints about the threats to Nucky's empire on several fronts, from law enforcement to rival criminals:

"Nucky finds his hold on Atlantic City weakened, first by state agents who arrest him for election fraud and ransack his office, then by members of his own inner circle and even his family, who align with Jimmy’s father, the aging Commodore Louis Kaestner, in an attempt to oust him altogether," HBO's statement reads. "Meanwhile, mobsters like Arnold Rothstein, Lucky Luciano, Meyer Lansky and Al Capone wait in the wings, looking for the chance to grab a bigger piece of Nucky’s pie."

Sounds like someone could use a drink.
