Elizabeth and Calvin find themselves deep within the outback of Western Australia, being pursued by Andrew's hired mercenaries as they continue their journey in search of where she came from.

Completely isolated and without help, they are found by a man named Tony, who takes them back to his place. There, they meet with another talking kangaroo named Brody, the star of a traveling MMA event, and the man who raised him named Jirra.

While Elizabeth tries to leave Tony's event and convince a reluctant Brody to join her, Mel isn't very far behind, and neither are Andrew and his mercenaries.
