While trying to make friends in her new city, Mindy runs into a nerd-turned-billionaire ex-flame from Princeton. She imagines the life of riches she could have had with him and questions her relationship with Danny. Meanwhile, back in New York, Danny and Morgan think they witness Lauren cheating on Jeremy with Peter, so they devise a way to spy on Peter.

Mindy has some big news to tell Danny but, just as she is getting ready to tell him, his father and half-sister show up for an unexpected visit. The whole crew is invited to Annette's house for the world's most awkward family dinner.
