Clare is living in apparent bliss with her artist boyfriend Lachlan, in a loft apartment with no furniture. But then her sister from hell comes to visit - and won't go away.

Kenny brings along his new girlfriend, Carole Anne, to the book group, much to the irritation of all the women.

Kenny is doing a book tour and the women of the Outer Isles can't get enough of the author of 'Peaks in the Mist'. Meanwhile, Lachlan seems to be taking an awful lot of interest in Clare's sister.

The group reads a dirty book, The Sexual History of Catherine M. Fist is impressed, and decides to organise group sex with Dirka. Lars and Bart. Meanwhile, Jean is mistaken for a prostitute while conducting research for her new book, and Clare meets Kenny's underage girlfriend, Harriet.

Jean has a party to celebrate her book deal. Kenny sings karaoke, Lachlan proposes to a reluctant Clare, and Janice gets very drunk and tells Rab she loves him.
