Sunday night saw another episode in the many storyline and sagas that make up HBO’s “Boardwalk Empire.” Last Sunday’s, “What Jesus Said,” featured Margaret (Kelly MacDonald) staring down some heat over signing off on withdraws from the account of the dead Arnold Rothstein (Michael Stuhlbarg) as well as Chalky (Michael Kenneth Williams) killing Buck (Dan Daily). The synopsis for the next episode, “Cuanto,” reveals much more action is coming next week.

The synopsis reveals that in her desperation over the impending trouble she may get into for her market playing with Rothstein's account, Margaret turns to her husband, Nucky (Steve Buschemi) to help with the problem. The episode will also travel to Chicago where Luciano (Vicent Piazza) will run into an old rival while meeting with Capone (Stephen Graham). Finally, in the latest installment of young Nucky’s story, the latest flashback will feature Nucky showing a young Eli (Oakes Fegley) “how the other half lives.”

HBO has also released a promo for the next episode of “Boardwalk Empire.” The sneak peek video shows Margaret and Nucky sitting down with her explaining her problem to him. He seems reluctant to help her, but with the synopsis promising that the estranged couple will find common ground, it looks like these two will finally be working together again. The promo also previews trouble in Cuba as Sally Wheat (Patricia Arquette) struggles to get business going in the country.

Watch the promo for “Cuanto” below:

How will Margaret and Nucky’s reunion fare? Will he be able to get her out of trouble or will he be roped into the mess with Rothstein. And who will be the old adversary that Luciano encounters in Chicago? Fans will have to tune in next week to find out. “Boardwalk Empire” airs on Sunday nights at 9 p.m. EDT on HBO.
