Episode 1

A young Irish couple, Sinead and Ronan, go missing from the small rural town in which they had been living and working, on New Zealand's North Island. Theo Richter, a detective from Ireland, travels to New Zealand to liaise with the local police and explore a possible Irish gang connection. He teams up with Diana Huia, a young Māori detective sergeant.

The couple’s disappearance means Diana must reluctantly return to her hometown and the painful memories that forced her to leave family behind. Theo has his own demons and is reluctant to share the personal reasons behind his sudden decision to leave the police force once this investigation is complete.

Together, the detectives try to figure out who Sinead and Ronan were and what happened to them. The empty house initially seems undisturbed, but evidence suggests either Sinead or Ronan may have been injured before going missing. Then Sinead’s company car is found at the base of the mountain, and a huge search and rescue effort gets under way.
