The fifth and final season of Boardwalk Empire is set to premiere on HBO this fall and the network dropped the first teaser trailer for the last batch of episodes this weekend. Most of the final season will reportedly take place a handful of years from where it left us in season four, shifting from the lavish and over-indulgent lifestyle of the Roaring Twenties to the hardships of the Great Depression. From all indications, we should expect some serious sh*t to go down.
