While Kai goes down to Water with a swarm of Moths to find food for the Lexx, Stanley struggles with Prince's proposition - blow up Water, or May dies again.

Gametown is attacked by Duke's forces in the stolen moths, though Kai manages to take back one and return to the Lexx with Bunny. Trying once more to go down to Water for food, Stanley decides they should go to Boomtown - the "all sex all the time" city... Meanwhile, Duke moves against Prince on Fire.

With their moth damaged in the battle with Duke's forces, Stanley, Kai and Xev are stranded together with the living Kai and Bunny on the deserts of Fire. They find an abandoned balloon, but it does not have enough fuel to carry them all to the nearest town until Kai volunteers to go the rest of the journey on foot. But then they come across Duke and Fifi...

Stan and Kai crash down on Water. Kai starts to sink towards the centre of the planet, while Stan drowns. The security guard is awakened on a beach by Prince, who tells him he now has to account for his life - prove that he deserves to spend the rest of eternity on Water, rather than Fire.
