As Bec, Frances and Sophie celebrate their eight million dollar lottery win, Jenny reacts badly to missing out. Despite Bec's best attempts to help talk Sophie and Frances into sharing, Jenny's over-the-top rant seemingly seals her fate. But when a series of events leads the girls to question the value of friendship in their lives, a collective decision is made to split the prize money four ways. Now all of them are multi-millionaires. And, more importantly, well and truly part of each other's lives once more.

Sophie grows attached to a drug- dependent baby whose addict mother has disappeared. Loved up Frances wants to show Zach a sign of her commitment and Jenny attempts to take her flirtation with Gabe to the next level.

With a fifteen year reunion looming, the girls explore just how far they've come.
