On Cluster, the capital of the league of 20 000 planets, a ship with the power to destroy planets lies waiting for it's master - "His Divine Shadow". But the soon to be executed rebel Thodin has his eyes on it too, and mangles the city's computer system while engineering his escape. Using the chaos that erupts, the death sentenced security officer Stanley Tweedle and the escaped "love-slave" Zev evade capture and eventually team up with Thodin... with the undead assassin Kai following, with orders to kill them all.

Zev decides they should go to Brunnis, the original home of the Brunnen-G, in hopes of finding something that can prolong Kai's life. When they arrive they find it barren, except from holographic messages left by the eccentric "Poet Man". As they enter the library, they are totally unaware that back on the Lexx Giggerota has sprung back to life and plots to steal it with the help of the remaining Divine Predecessors.

Xev demand they investigate an abandoned world, still transmitting TV signals. The computer host offers them parts in different TV shows, though they had better get good ratings or they'll end up canceled...

Norb is found floating alone in space, nearly out of oxygen he is taken aboard. To their horror, it turns out he has been modified by Mantrid, and releases a handful of drones who begin tearing the ship apart, building new copies of themselves.

Stanley's broadcast for help against Mantrid brings them in contact with Brizon, designer of the Lexx and Mantrid's teacher. He claims he can shut down the drones, but can he be trusted?

With only hours to go before Mantrid has demolished the universe, Stanley comes up with the idea of creating their own army of drones based on 790 to combat Mantrid's. But is it too little too late?

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.

Xev and Kai go to Fire to confront Prince about Stanley's life essence. When he refuses to give it up, Kai jumps down into a well to the planet's core hoping to retrieve it. He winds up on the beach, with Prince taunting him that he's now trapped there for eternity, unable to help either Stanley or Xev.

In the near future, an alien spaceship is discovered orbiting the moon. At the urging of his top advisor, Prince, the president of the USA makes contact in secret with the aliens' leader: A strange man who introduces himself as "Stanley H. Tweedle". Unfortunately, the contact does not go well, but Prince is prepared, suggesting they send an insane killer up to the ship in a space shuttle...

About to be destroyed, Prince requests Kai complete their game of chess, but with this time with real stakes. Should the undead assassin win, he'll get his life-essence back. Should he loose, Stan and Xev's lives are forfeit.

An asteroid mothership appears out of the blackness of space. A metal hatch opens and a tadpole-like creature shoots out and heads for the Lexx. Stan awakens from a nightmare in which he was eaten by Lyekka and discovers that the alien mothership is hovering outside of the Lexx. Before he can finish telling Xev and Kai what he has discovered, an alien who has assumed the physical appearance of Lyekka from Stan's dream appears on the Lexx.

A huge alien asteroid mothership plummets to Earth and crashes into the Pacific ocean, causing a great disturbance off the coast of Japan. Inside, Lyekka prepares to devour "Japaneseland". Kai and Xev take a moth down to Earth to retrieve Vlad's cryopod control unit, which will replace the broken one on the Lexx. Fearing that Lyekka will consume the entire universe if she is not stopped, Xev and Kai decide they must take action to stop her.

Prince visits the Lexx warning of "Earth's date with destiny". Emotions abound as Kai begins to feel again and the Lexx's health is ailing. As the alien mother ship has reached Earth.
