Dimity's devious strategy to stop Amber having Julian's baby, pushes Arthur past his snapping point. Constance reveals herself as a master manipulator to dish out her kind of justice to Ralph and Horse, and news of Caroline's death spurs Stuart to kick-start his life in an unexpected direction.

Constance reeling from the news that Horse is her real father and going into emotional freefall, drifting away from family life and worrying Sharon and Amber. She confronts him, a tactic that backfires and puts her in increasing danger. Sharon attempts to warn Horse off her youngest daughter, to get him out of their lives, but she realises that he is now so inextricably connected to them all, that she can't see a way free from his malign influence. But Constance can. Meanwhile, Stuart is horrified that Dimity's book features explicit accounts of their love life, sexed-up on the advice of Hemi, who is renting Julian's room. But Dimity is preoccupied by the shock of learning that Amber is carrying Julian’s baby, especially when Arthur makes it clear that any interference from her will have desperate consequences.

Dimity discovers new ways to get compensation from Bonnie, using the loot from the sale of Bonnie's home to save her own place, while exploiting her as a personal assistant. Dishonesty costs Constance her surveillance job, but when she strives to win it back by completing a dangerous assignment, what she uncovers leaves her shocked and confused. And under Stuart's care Amber faces the consequences of her reckless personal life.

Just as her finances collapse, Dimity has an epiphany inspired by her dying friend Caroline, and glimpses her future destiny. Thinking fast, she strikes a deal with Bonnie and Jase, which saves her home but binds them into a devilish contract. Meanwhile, Amber's affair with a journalist explodes when he publishes her family's secrets, alienating Amber from her mum Sharon. Constance pursues a secret life as an investigator which brings her in contact with the dangerous Horse. And Arthur makes a terrible bargain to keep his family together.

Stuart bears the full force of Dimity's sky-rocketing stress-levels when she receives a 24-hour ultimatum from the bank to sort out her finances or lose both Ponsonby homes. Into this fraught atmosphere comes Caroline, Dimity's old best friend and Stuart's one-time lover, now with just weeks to live, on a mission to make peace with the past. Julian, freaked-out by his parents and desperate to win back Amber, seeks refuge next door with Arthur.

Dimity is conflicted by the news that Julian's life was saved by Arthur Short, and now she must contend with the mysterious fire which has left their Kumeu house in cinders, threatening her financial masterplan. After Pita’s death, Amber soothes her grief in an affair with an older journalist, breaking Julian's heart. Sharon is torn when Dara insists she must choose between her or her interfering family, and she finds herself drifting back to her dangerous old haunts. And Bonnie lives in terror awaiting the moment when Dimity figures out just how guilty she is.

Dimity's back gives out in a tug-of-war with Arthur, and Bonnie's husband Jase comforts her with a backrub. Taped by Ollie, this is dynamite in Constance’s hands. Sharon Short attempts to sort out her wayward daughter but her lover Dara goes on the attack.

Dimity is on a natural high as her notice to evict Arthur ruins his birthday. While Dim celebrates with a new Ponsonby hairdo, Constance starts to work her devious magic behind the scenes, grooming Dimity’s seven year old Ollie as a secret agent and planting him back inside his own family as a mole. And Arthur discovers just how dodgy his mate Ralph really is.
