One year on, Amy, Britta, Cody and Kevin return to the beach where they first made their pact, Cody's big day brings heartbreak and surprise. It seems everyone believes in fairies.

Amy still doesn't seem to remember the best night of Kevin's life, but Kevin insists he's glad; this way nothing changes. Besides he's got a hot new lady in Wanda who seems on his wavelength about keeping it casual. Business at Finders Seekers is good, but Larry is in rehab and Amy is still a long way from achieving her goal. When Brad drops by with news that her old house is soon going back on the market, Amy wonders how she can get the money together she needs to buy it. Britta's mum and her new-old flame, the one legged Ron, throw a surprise wedding before sailing off into the sunset. But then terrible news; there has been a storm and Fran and Don are missing.

Everyone pitches in to solve Cody's man problems. Britta gets a lucky break.

Britta gets to know a long-lost relative, but is Don really her father? Meanwhile, Cody's relationship with rugby star Eli takes a giant step forward, and Amy struggles with Cody's new life.

Britta digs for dirt on Eli, Amy and Brad exchange mixed messages, and Cody makes an alarming discovery.

Britta is struck by tragedy, Amy gets the wrong idea, and there's a new McMann in town.

Kevin's wedding approaches, but his big admission has far-reaching consequences. Cody is blindsided when her parents announce they are moving to Perth and want Possum to come with them.

Amy, Britta and Cody are three young women suffering their quarter century crisis: 25 and what have they achieved? They make a vow that in one year they'll each fulfil their ambition. Their mate-since-childhood Kevin, admires their pluck but, to be honest, since Amy, Britta and Cody are currently Tragically Poor; Tragically Unknown; and Tragically Single, he reckons it's going to be a bit of an ask.

Brad is about to be a dad; Britta's new object of desire leads to desperate measures and Leo; Cody receives some upsetting news from Eli; Kevin scores a date with someone he knew from school.

So it's another January, but one year on — and this is where we find the Go Girls: Britta has been through a very big change. In fine McMann tradition, she is the solo mum of a little girl, now four months old. Cody is running the garage and living with Possum. But on the romance front things have changed a lot. Amy is back on the Shore — and she's a woman with ambitions. Brad returns, but a broken heart and overseas travel mean he's a changed man. Olivia and Joel are doing well with their music and had a minor breakout hit that's been sold for an ad. Kevin has been married to Amanda for more than a year, but he's hardly seeing his friends these days... Kevin is back in town with bombshell news, as Britta has big news for Kevin. But when bombs go off, someone is bound to get hurt...

Life can go in very different directions as Cody and Amy both discover when visitors rock their world. But can a frock sale really make that much difference? In one version of our sliding doors, they do. Cody's new frock causes a fight with NSB and a rematch with Eli, who ho has come to ask for a divorce, but is torn... In the version where the gals don't go shopping, Amy goes home to find her mother in bed with her boss Brendan...

Cody makes a big decision, Amy gets a new partner, and Britta considers a different kind of fame.

Our heroes are facing the end of their 20s — the downhill run which can only end in (oh god!) 30... For some it will mean one last stab at freedom; for others, time to try and settle down. But even best laid plans lead where you least expect them. This year, the quests are sorted. But has Kevin really found the perfect woman? And can Cody defend Gwen against a witch?

When Brad gets surprising news, Britta confronts the green-eyed monster. Kevin gets an offer that could ace his quest.

Kevin has family! But this particular cat causes havoc among the pigeons, and Cody needs cash for a good cause.

When it comes to love, a lot can change in a month — as Kevin, Cody, Olivia, Brad and Britta all discover.

Amy gets a foot in the business door but Kevin smells a rat. Sparks fly when Britta meets up with a former flame.

Britta's quest to be famous at all costs sees her applying for a new reality TV show called "Mother v Daughter". After being called down to the studio, her hopes are high, but she quickly discovers she's actually been enlisted as a party fairy for the executive producer's young boy. Amy's quest to become rich involves the same executive producer — she becomes her personal assistant, hoping to discover the ways to fame and fortune behind the camera. A new man enters Cody's life — just as she hoped. Problem is — he's Possum's teacher and he's married.

When Amy's ex Brad loses his high flying finance job, he turns to her for comfort. But green-eyed Kevin's not having any of it; he tips off Brad's wife, and resident superbitch, Angelina about Amy and Brad's secret meetings. Then, Gwen drops a bomb when she reveals to her family that she's been diagnosed with Alzheimer's.

After a string of hideous experiences, Cody puts on a brave face and shows up to yet another blind date only to be stood up. As luck would have it Ben is there and the pair end up having a date, sort of. Amy is working hard for Antonia and manages to pitch some new ideas. When she realises that Antonia has renamed one of her ideas and claimed it as her own, Amy takes this in as a valuable lesson, but Larry is less sanguine. Kevin ponders the nature of luck vs circumstance but when he finds himself at the bar with a very drunk Amy he decides to seize the day and declare his love. Unfortunately, all Amy hears is a declaration of undying friendship.

The incredible has happened; Kevin has slept with Amy. The next morning, Kevin is in seventh heaven but lost in the hangover from hell, Amy doesn't remember that they even did it. Cody and Eli are steaming ahead with engagement plans and parties, photo shoots and happy families. Everything on the surface looks perfect but there's something amiss in this fairy tale… how long will Cody be able to ignore the truth? Amy's world starts to unravel when she discovers her Dad's not as perfect as he makes out. In a drunken stupor he writes off a car, and even manages to give Jan a blow to the face. Will Amy keep standing by her father after all this?

A new year, new resolutions; the Go Girls embark on another epic quest. And this time, they decide on new and bigger objectives… Heartbroken and in debt, Amy is taking her mind off her problems with meaningless sex. Britta's intervention with Amy gives her a realisation, having slept with half of the North Shore, she now wants something better. Cody returns from honeymoon, but the gay rumours surrounding Eli haven't gone away. Cody realises now that getting married was the easy bit, and staying married is a lot harder. Kevin decides this year he is aiming higher in all respects.

Kevin thinks that the truth is sometimes better not being told — as Amy reels from the news that her mum has kicked her Dad out because he once slept with one of her friends. Surely not Cody? This tests Amy's resolve to help others, but she can't let it go, especially when she works out the real secret — the truth about Possum's paternity. Cody tries to damp the flames of the terrible rumour. She's relieved when Eli supports her in wanting to shut this down and say nothing. But when Eli learns the truth, Cody finally realises she'll have to man up and tell all, painful as it might be.

Loyalties are tested, and who comes first — friends or family? The return of Amy's old school friend stirs up a catfight; while Britta finds a love guru.

Anyone can do anything — unless they're two of life's great under-achievers; Kevin takes the plunge and Britta surprises everyone.
