HBO has given fans our first glimpse at what's ahead for Nucky, Margaret, Jimmy and company on season two of Boardwalk Empire.

Without giving much away, the following trailer does feature KKK members with Gatling guns, along with Steve Buscemi's main character threatening to ruin his competitors. But it's safe to assume this won't be easy...

The second season of Boardwalk Empire premieres in September. It will feature Michael Zegen and William Forsythe in recurring roles.
