After being targeted by hitmen and narrowly escaping her murder, corporate CEO Stella Heikkinen and her two kids are sent to a small and remote Tasmanian town, where the locals are suspicious of their arrival.

As Stella and her kids become more acquainted with Mystery Bay and its inhabitants, she is confronted with the dangerous realities of her situation. Stella meets Frankie McLeish, the town matriarch.

Frankie puts Stella on trial in front of the townsfolk. Meanwhile, Airini gets dangerously close to solving the case and instructs Stella to prepare to leave Mystery Bay.
