After a wild night of hard partying, Sarah and Rachel stumble into a spiritual commune for a free sausage sizzle. There they encounter the Purple Fire God who tells them their destiny.

Sarah, Rachel, and Lucas head to Planet Bali for Sarah's sister's wedding and are surprised to discover the identity of the groom. But the bride's intentions are far more sinister than tying the knot.

Sarah throws a Wollongong High School reunion to show off her blossoming new garden, but the success of her old school mates only deepens her crisis of self-worth. Rachel invites a bunch of randoms who turn the party to chaos.

Girls' movie night watching an art house flick starring a hot young actor leads to a wild romantic dream for Sarah, a dream which Rachel is determined to sabotage.

The gang travel 300 million years back in time using Lucas's time machine, where Sarah tries to rescue the Australian megafauna from an impending comet using skills she's learnt from a self-help guide.

On a quest for a tale of familial lore, Lucas seeks out the story of how Sarah's parents met; he hears a ripping yarn of fair maidens and reckless bravery set in Ye Olde Wollongong, where dad needs to save mum from an arranged marriage to a boulder.

Sarah posts a picture of her garden, and it leads to her becoming an overnight internet sensation and causes a paradigm shift; Rachel's jealousy drives her into the arms of dead Mega-Bilby.
