The episode is set during Saint Patrick's Day and progresses the relationship between Nucky and Margaret, while also showing how Jimmy is haunted by the consequences of the life he now leads.

Margaret wakes to see men working for Atlantic City ward boss James Neary offloading barrels of illegal beer into a motor garage behind her house.

The agents initially dismiss the operation as one of hundreds in the city that they lack the resources to shut down, but Margaret is able to get Van Alden's attention by mentioning that Neary works for Nucky.

Angela angrily rejects her offer and leaves to meet a "friend", who is later revealed to be the owner of a photography studio on the Boardwalk she grew close to during Jimmy's war service.

At the dinner, Eli's speech turns into a disaster when he brings up the Easter Rising, nearly triggering a violent brawl among the attendees and forcing Nucky to intercede.

Van Alden, acting on Margaret's information, raids the dinner, arrests Neary, has him paraded before a gaggle of reporters, and has the doors to the clubhouse locked and chained before overseeing the smashing of beer barrels.

The episode features the show's strongest character interactions yet, as Margaret's role in the Temperance League threatens both Nucky's political and criminal enterprises as Federal Agent Van Alden applies pressure to both."
