The Gone, Season 2

When an Irish couple disappears from a remote New Zealand town, visiting detective Theo Richter (Richard Flood, Grey’s Anatomy) teams up with local officer Diana Huia (Acushla-Tara Kupe, Shortland Street) to investigate. What begins as a missing persons case soon stirs up old fears in the community, with whispers of a connection to a string of long-forgotten murders. As the detectives navigate cultural divides and buried local secrets, they uncover far more than they expected in the quiet town of Mount Affinity.

Episodes will air in November as follows:

December 1st
- Episode 5: A convicted criminal linked to the case escapes from prison as Diana and Richter track down their latest suspect.
December 8th
- Episode 6 (FINALE): With Mount Affinity locked down with lead suspect Frank Pastor on the loose, Diana and Richter must solve the case before the Mountain Murderer gets to their next victim.
