With her major exam looming, and rumors that a marriage proposal might be brewing - Heather's world is blown apart when she learns of Ben's betrayal.

Heather's in a funk, hitting peak mediocrity, just tolerating Ben. Desperate for a circuit breaker, she accidentally sets Ainsley and Harry on a mission to get her back on the dating scene.

Harry finds himself charged with organizing Ainsley's questionably-themed 'white-party' Hens, and Simmo's 'fire-on-the-land' Bucks.

It's Ainsley and Simmo's wedding day, Ben is determined to be there for his best mate Simmo and the love of his life, Heather. Over the course of the day, truth bombs will detonate.

Hosted by Harry, Manju is already somewhat sullen at her seventieth birthday gathering, when an errant comment subsequently leads to that sullenness turning to belligerence specifically toward Harry. Manju, being her manipulative self, makes a pronouncement intended to make Harry feel guilty enough to apologize, that pronouncement which Harry doesn't believe she will carry out to its end, Harry in turn calling her bluff. Feeling like he has perhaps gone too far, he is convinced by Heather to double down on that bluff or else have her know that she will always be able to manipulate him. With those plays going into night leading to both Harry and Manju having little to no sleep, something happens in the morning to change the face of their standoff. Meanwhile, Stuart is on his way back to Melbourne on a business trip, Liz who, on their last telephone call, stating that they need to talk in Stuart's belief that she had an affair. Liz has to decide exactly how she is going to broach the topic of the "issue" with him. And Ben is finally going on a date about which Ainsley discovers. It isn't so much that he has this date, which he doesn't see as such, but who the date is with. Regardless, Ainsley in particular has to decide if or what to tell Heather.

Ainsley receives news from a more distraught than usual Cheryl that Des has passed away. In Ainsley's priority of being the nurturer and despite her feelings about Cheryl, Ainsley decides to invite her to stay in the house for however long she needs while she is in town to deal with Des' affairs, and in support for "family". Ainsley also issues the directive that no one is to tell Manju about Des in Ainsley not wanting to burden her with more bad news considering her health, hiding it from her which may be difficult especially due to Cheryl's boisterousness. Of everyone in the house, Ainsley seems the least emotionally affected by Des' death, outwardly due to that nurturing taking priority, but inwardly due to her confusing relationship with her father, that confusion especially since Cheryl came into the picture intimately which was even before Ainsley's mother's passing. The situation gets even more confusing for Ainsley shortly after Cheryl's arrival, the specific stressor which Ainsley will have to deal with both emotionally and legally. Meanwhile, Ainsley's decisions have an unexpected negative effect on Liz and Stuart's already crumbling marriage. And Cheryl's arrival leads to a game of musical bedrooms, Heather the most obvious person to relinquish hers in having Ed's as a place to stay where she is most nights anyway. However due to a family situation with Ed, Heather decides to stay in Colin's granny flat. As the one now geographically closest to Heather, Colin discovers that Heather's outward reason for not staying with Ed was a lie which he figures indicates problems between Heather and Ed, such news which he has to share with his fellow "Heather spurnee" Ben.

Heather's newfound serenity is skewered when her graduation day devolves into chaos.

After a spectacular indiscretion in his workplace, Harry's career is well and truly on the line. Facing a professional investigation, he is receiving strategic advice from Liz, whilst trying to hide the whole situation from his suspicious mother.

Liz is bearing the brunt of Harry's anger and grief. In an effort to rescue their friendship, she throws herself at the mercy of the last person on earth she would ask for help.

While everyone in the house is frantically preparing the house to be sold, Heather pulls after finding out two housemates are moving in with her ex-Husband. Harry scatters his mum's ashes with Liz, Simmo finds out about Ainz's pregnancy.
