Series two will reunite us with Detective Sergeant Mackenzie ‘Mack' Clarke, who's longing to get back to the UK and the life she's always craved. But for now she's stuck in Dolphin Cove, dodging her ex-fiancée Glenn's upcoming wedding after overhearing his unexpected declaration of love in the series one finale - a confession that she can't unhear.

Luckily for Mack, her compulsion to solve impossible cases serves as a great distraction, and there's no shortage of murders to investigate. From the literary world to state-of-the-art shark labs, dating apps and rock concerts, Mack and her team face challenging mysteries with their unique blend of humour and tenacity. But Mack's biggest challenge of all? Finding a way to exist in Dolphin Cove as the ultimate outsider.
