In order to take her mind off of her heartbreak, Erica takes a trip to Los Angeles to see her best friend, Lainey Lewis, and they end up getting the band back together for a gig. Meanwhile, after getting caught taking part in an underground poker game, Adam gets sentenced to Pop-Pop duty, which turns out better than expected.

Geoff shares with the JTP that he is planning on asking Erica to marry him and gives them the engagement ring for safekeeping. Like any good romantic comedy, several miscommunications and misunderstandings between Geoff and Erica's friends and family result in a potential derailing of the proposal, forcing Adam to step in to keep the couple's special moment alive.
