A group of people whose loved ones have gone missing discover they have become part of a mysterious cult, living in an isolated community in a remote part of New Zealand.

With Daniel missing and a threat to stay away from the police, Michael and the Liberators are learning that to get their people out of the compound is going to require more risky measures.

Nathan turns up unexpectedly at The Glen, and Michael and the others are shocked by his condition. It becomes increasingly clear that the Two Gardens doctor has some questionable methods.

As Saul, Edward's right hand man, gets closer to finding the Liberators, we learn some of his dark secrets, and, at The Glen, the Liberators meet the person who bugged them.

Armed with the information that Jenni is in grave danger, Frances goes on the hunt to get answers. She enlists Sophie and Gina then heads out on a risky search.

The discovery of Jenni shocks the Liberators to the core, and they decide that to get information from the source, they need to kidnap Cynthia Ross.

Michael is invited into Two Gardens to meet Edward face-to-face. But while he's in the compound, it becomes clear that the danger to the Liberators is also coming from inside The Glen.

Having returned to Two Gardens, Cynthia realises that her plans will need to be sped up. But when an untrusting Edward is hesitant, Cynthia decides that she needs to take matters into her own hands.

Trapped in Two Gardens, Gina desperately tries to convince a very sick Andy to leave with her - and with the mysterious 'Commencement' approaching, can she get him out before it's too late?

A reluctant Michael agrees to Sophie's plan to shoot Edward North. But things don't go to plan and it becomes clear that Sophie's mission is very different to that of the Liberators.

Following the shooting, Edward has become a dangerous man - paranoid and determined to see his plan out at any cost. He takes action to start the Commencement by making some duplicitous friends.

First hour of the two hour finale. Michael returns to find the Liberators taken, Sophie's lies are about to blown apart, and 'The Commencement' begins.
