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.

Sarah is kidnapped by bees whilst tending to her flowering garden and taken to their honey castle where she is made Empress. Rachel and Lucas come to the rescue, only to find that she is violently drunk on power. And honey drugs.
