The fabulous foursome are back and raring to embark on more adventures of the romantic kind. However, with a new member thrown into the mix, namely Miranda's baby boy Brady, life has some major changes in store for them. For Miranda it's all about breastfeeding and loosing her baby fat; newly-divorced Charlotte takes a tip from Samantha's sex book and starts enjoying 'just sex'; Samantha ditches her boyfriend and gets up to her usual sexploits then even more shockingly offers to baby-sit Brady. And Carrie? After a spate of dire dates she turns her attentions to her beloved New York and to writing a book which, after a fabulously glamorous book launch, turns out to be a massive success. Life may have its ups and downs but there is never a dull moment when you're part of the ultimate glossy posse.
