Despite giving up coffee and alcohol, taking up colonic irrigation and Buddhist chanting, Edina is panicking about a fashion show she's organizing, Princess Diana has turned down an invite, and the only celebs who can be bothered to attend are Sinitta and Anne Robinson.
Edina needs to get slim quickly as she's expecting a visit from old friend, Penny Casper-Morse, who used to tease her about her weight. She contemplates a regular fitness routine, but then Patsy suggests something much easier... liposuction.
Edina and Patsy go on holiday to France but the luxury they've booked turns out to be the ramshackle cottage. Unable to negotiate the local shops, Edina calls up Saffy for help. Bubble turns up, too, with news that Edina's interior design business has hit problems.
Banned from attending Saffron's college open day, Edina sulks in her brand new isolation tank. But she's got a few tricks up her Lacroix sleeves yet.
Eddie is turning 40 and Saffy organizes a quaint family get-together for her involving Mother, Justin (Saffy's father), Justin's lover Oliver, Marshall (Eddie's son Serge's father) and his new wife Bo. However, Eddie has developed a complex about her age and refuses to participate in the celebrations.
Patsy actually visits her place of work, a fashion magazine where she is the 'Executive Fashion Director'. She takes on the job of organizing a fashion piece for a morning television show but when all the models drop out and refuse to wear the clothes, Patsy is forced to suck up to Saffy and Mother to get them to appear on the show. Meanwhile, Edina has a date with long-lost boyfriend Hamish.
