Sharon and Tracey have not spoken for years, since Sharon called Tracey's new husband Ralph a bad lot - which he was, hence Tracey's divorcing him. Now, in a meeting engineered by Tracey's schoolboy son Travis, they both turn up for a book signing by sexy authoress Foxy Cohen - who is actually Dorien. Appalled that Sharon is living in a dismal flat Tracey invites her to stay again, but then Dorien arrives. Served with a writ for plagiarism and with her assets frozen, she becomes Tracey's next lodger - to Sharon's annoyance. And to add to an already full house, Garth returns unannounced from Australia with his new wife Marcie and her little daughter Poppy.
