Patsy and Eddy are forced to clean up the house in preparation of Saffy returning from Iraq. When Saffy returns, she has a big announcement.

Eddy and Patsy organize a book club to meet famous people, but no one is interested in reading anything except celebrity gossip magazines. Eddy has recurring nightmares about Saffy's midwife, who delights in teasing her about them. She's very unhappy about the expected grandbaby until she learns the father is black... after all, a mixed-race baby is the greatest accessory, the "Chanel of babies."

When Eddy converts her bomb shelter into a panic room, she and Patsy accidentally get locked in and, not knowing the access code, have to wait until the system resets and the door opens.

Edina and Patsy spend the weekend at a snooty lodge in the country and become so bored, they create their own version of fun. Meanwhile, Saffy has her friends, Emma and Sarah, over for a baby shower and Sarah becomes obsessed with Emma. The weekend ends with Emma getting a restraining order and an unexpected turn of events for Sarah.

The big day has finally come and Saffy goes into labor. Everyone is there except the midwife who is unable to get into the house after the power goes out because the doors, which lock electronically, cannot be opened without electricity.

Edina's 'new' boyfriend Pete, who she and Patsy knew growing up, works at Abbey Road Studios and uncovered some "lost tapes" of the Beatles. They throw a party to play them in public for the first time and things don't quite go as planned. Elton John does a cameo.

Saffy grudgingly agrees to let Eddy babysit Jane while she and John go to lunch, but as soon as they're gone, Eddy whisks her off to the zoo where Patsy has arranged for her to be part of a photo shoot with famous photographer, Jean-Paul Gaultier. Saffy's anger at her mother is softened when Eddy confides she and Jane bonded; that is, until Saffy makes a shocking discovery.
