Edina joins a New Age commune, but she struggles to fit in and quickly becomes bored. Patsy finds herself disillusioned with her new job in New York due to creative differences with her co-workers. Saffron settles into university life and Mother spends her days at the Monsoon house, drinking champagne and ordering items from the shopping channel. After realising that their lives are not the same without each other, Edina and Patsy happily reunite on top of Carnegie Hall Tower before returning to London. Back home, Mother has been arrested for squatting and credit card fraud. A flashforward to 25 years into the future provides a glimpse into the lives of Edina, Patsy, Saffron and Mother.

Bubble accidentally emails Edina's clients' details to nemesis Claudia Bing, who poaches most of Edina's clients, including Twiggy. Patsy—who has recently been diagnosed with osteoporosis—and Edina are horrified when Saffron forces them to attend a Menopausals Anonymous meeting organised by her. In order to save her business, Edina dupes Claudia into buying her TV company—which currently has no programmes—while Claudia also agrees to return several high-profile clients. Saffron has a terrifying nightmare in which Patsy threatens to impregnate herself with a vial of Mick Jagger's sperm unless she is allowed to move into the spare room.
