The year is 1989. The Wall is about to come down, Phil Collins is bothering the charts, and thanks to Crocodile Dundee the world is in the midst of a short-lived infatuation with Australian culture. The same can't be said for Simeone Cooper, a fabulously wealthy London housewife who'd rather forget her antipodean adolescence. However, when fate brings her and her two teenagers back to her hometown, Simeone must revisit the past and finally face up to the friends and family she left behind, and only ever knew her as "Sammy".
Sammy and her kids are coming to terms with the culture shock of life in Newcastle and the possibility that they may not be returning to London any time soon.
In the midst of being bullied at school, Sammy's son Lenny strikes up a friendship with fellow misfit Bo, and they bond over their shared longing for girl next door.
Wanting to use Sammy's 'posh English accent' to impress some big-shot investors, MP Chris brings Sammy along to his business meetings in Sydney.
After a harsh realisation, Sammy aims to reclaim her worth by helping at the school disco. But the dance soon turns into a debacle.
Sammy gets good news about her husband's estate. But as she plans their escape, things prove far more complicated than she imagined.
Sammy flees Australia for London with the hope of claiming back her opulent lifestyle - and keeping her children away from the fall out of Terry Harris' 'disappearance'.
Det Sgt Fairbank makes another visit to the Cooper house to interrogate Jean and Jim; Bev looks to turn her life around before the impending birth of her baby; Chris strikes up a working relationship with a journalist.
Sammy's time in London comes to an end when she receives a call instructing her to return to Australia as a witness in the Terry Harris missing persons case.
Bev realises that the Coopers need her to lie to the cops and looks to profit from their desperation. However, Bev's exploitative behaviour unravels when Jim comes to her side in her hour of need.
Fairbank discovers an unexpected new lead that puts Abby, Tess and Lenny at the centre of his investigation into the disappearance of Terry Harris.
While helping evacuate nursing home residents, Fairbank stumbles across Mrs Atkins chattering about vital case information. As night falls, the Coopers struggle to move the evidence.
