After the shocking events of the previous episode, "Boardwalk Empire" Season 5 gears up for more action in episode 7. There is just one more episode left before the finale that will bring an end not only to the season but also to the show. [Spoiler Alert!]

The long impending mob war is all set to begin in the next episode of "Boardwalk Empire." The main targets will be Lucky Luciano and his partner Meyer Lansky, who want to change the way things are run by the mob. The promo video of the next episode shows that even the boss of all bosses, Salvatore Maranzano, is looking to kill Lucky and his crew.

The previous episode showed Mickey Doyle assembling a few men for a mob war. Nucky Thompson had promised Johnny Torrio previously that he would not rest till he saw Lucky and Meyer in their graves. The promo video of episode 7 shows Nucky meeting Lucky at a deserted place. Does Nucky want to come to an understanding with Lucky?

After the shocking death of Nelson Van Alden in the previous episode, Eli Thompson has nowhere to go. He will meet with his son in the next episode. Willie Thompson, played by Ben Rosenfield, is seen asking Eli what he wanted in the promo video. Will he be the next to die in "Boardwalk Empire" Season 5?

The producers have shared two videos in memory of the two dead characters—Chalky White and Nelson Van Alden. The videos show the characters' story from the first season right until their deaths in season 5. Chalky White's rise to power and his fall later can be seen in the video. Nelson's story from when he was an agent with the Internal Revenue to his murder of a fellow agent and finally him joining the mob before his death are all shown in the video.

"Boardwalk Empire" Season 5 episode 7 airs on Sunday Oct. 19, 2014. The episode will set the stage for the grand finale on Oct 26. The episode will also reveal more details from Nucky Thompson's past, when he was working for Commodore Louis Kaestner.
