Fig returns to Eden 2 with a treaty to share the preppers' land in exchange for the luxuries of his new white prepping community, Shangri-La.

Charlie's mother arrives at Eden 2 to reconnect with her, and a secret mission to take on Monty's claim to the land.

Charlie accidentally locks the preppers in the Eden 2 bunker and they must decide who should be sacrificed to ensure enough air remains for the group.

After finding a skeleton buried at Eden 2, the preppers kidnap an Aboriginal archaeologist to determine who the bones belong to.

The preppers attempt a First Nations survival exercise, but after they get lost, they find themselves being tracked by a mythical creature.

Escaping the fallout of a personal cataclysmic event, Charlie, a young Australian Aboriginal woman, finds herself at the centre of a mismatched community of doomsday preppers.
