With a milestone birthday approaching, Porsha makes moves to celebrate and settle into a new life with her fiancé, Simon. Meanwhile, her family begins to question the speed of her engagement, and Dennis struggles to fully support Porsha's love life.

An unexpectedly emotional cookout leaves the whole family with questions. Porsha grapples with the future of her blended family, and Simon is put on the hotseat by Porsha's protective tribe. Dennis navigates his role as father and co-parent and Mama Gina turns a lunch with Porsha into a real "tea" party.

As the entire family prepares for their trip to Mexico, Porsha and Lauren focus on getting Simon and Dennis to join the retreat. Lauren's plan for family healing comes to a screeching halt when Porsha finds out Dennis' intentions for coming on the trip may not be genuine as she thought.
