Despite giving up coffee and alcohol and taking up colonic irrigation and Buddhist chanting, Edina is panicking about a fashion show she's organising, 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 because 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 servants quarters. Unable to negotiate the local shops, Edina orders Saffy bring food from England. Bubble turns up too, with news that Edina's interior design business has hit problems.

Eddie gets carried away with a new fad and buys an Isolation Tank which she likes until she finds out that she isn't the only person who has one. While spending most of her time in the tank, her claustrophobia causes her to dream of an alternate world where Bubble is efficient and Saffy has interesting friends.

Eddie is turning 40 and Saffy organises 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.
