Everybody always knew that Alice and Louis would eventually get married, but now that it’s actually happening...what does that mean for everyone else?

Despite her best efforts to stay patient, Margot is disappointed again and again by Clare’s missed opportunities to come out to her bigoted mother. Rose always took her relationship with her longterm boyfriend, Adam, for granted - but when he claims there's nothing he wants more than locking it down in marriage, she fears their free and easy bond may be in its final hours. Lawrence finally has a chance with the newly single Dana, but her hangups over getting back into a relationship threaten his long-awaited moment with her. And on the outside of all of this is Simon, with no date to the wedding, no particular love interest, and no particular interest in love itself—unless meddling with it can save him from being the only single friend.
