February 1924. Nucky, preferring to stay in his room up in the Albatross Hotel and away from the boardwalk, comes to a peace agreement with Masseria and Rothstein.

Gillian, still an addict but desperate to get her grandson back, is resorting to prostitution until a stranger shows up with a better offer.
