An ordinary Kiwi couple have no idea their lives are about to change when strangers arrive in the Far North; a ship sets out from Hong Kong, carrying precious cargo and a Tongan-Australian gang land in Aotearoa for a once in a lifetime drug deal.

The stranded crew ration their remaining food and water carefully, while waiting to be rescued; drug boss Cai arrives in New Zealand; the gang reach out to Ed for help.

The gang's attempt to launch a rescue mission ends in disaster; the stranded crew face more dangerous days ahead without any drinking water; Ed and Heather make a shocking discovery.

Ed and Heather collect evidence of the gang's suspicious activity; tensions rise between the gang and the Chinese; Captain Jin makes a grim deal with Cai.

The rescue boat finally launches successfully with much-needed fresh water for the dying crew; the gang bring in the laundry, and Ed and Heather do what they can to derail the drug deal.

Ed and Heather confront the cops; the gang check in to a campground to lie low; Captain Jin and her crew face a devastating loss.
