Return to Paradise follows DI Mackenzie Clarke (Anna Samson), an Australian ex-pat who’s made a name for herself in London’s Metropolitan Police for cracking uncrackable murder cases. When she is accused of tampering with evidence, Mackenzie returns to Australia, back to the last place she ever wanted to be – her hometown of Dolphin Cove. Having fled the town six years ago, infamously leaving her ex- fiancée Glenn (Tai Hara) at the altar, Mackenzie is not welcome here.
