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.

The Lexx is forced to land on a planet to eat and replenish its energy supply. While they wait, Stanley and Zev go outside to bury Kai, who seems to have run out of the protoblood that kept him functioning. On their way back, Zev insists on investigating a structure. Too late they discover that it is filled with insane people obsessed with getting "clean bodies" to make "pattern."

Kai is running out of protoblood, and a desperate Zev forces Stan to set course back to the Cluster through the fractal core. When they arrive they find they entire planet barren - everybody killed in "the cleansing", in preparation of the birth of the Gigashadow.

Possessed by remnants of His Shadow, Kai convinces Stanley to return to the ruins of Cluster in the Light universe to search for more protoblood. They find insect larva, but it is dormant and can't produce protoblood. So Kai insists on taking it to Mantrid, an infamous scientist that might be able to revive it.

Stanley messes up the cryo-stasis revival procedure, and Kai reverts back to His Shadow's assassin for a moment, puncturing Stanley's heart. With Stanley in stasis they locate an orbital medical facility, though without any funds, they are turned down until Zev threatens them with the Lexx.

The Lexx intercepts the porn-flick a nearby space transport is running as entertainment, and Stanley orders the ship to head for the source - believing it to be an actual distress signal. But when they arrive, they find only the wrecked remains of the transport, with the hazardous material it was transporting leaking out.

Stanley discovers much to his dismay that they aren't alone on the Lexx. A family of hillbilly farmers has been living there in hiding, and decides to seize control of the ship and return to their home planet.

Going inside, the crew discovers a theatre troupe performing the history of the Brunnen-G. They ask Kai to play his part in the story - the starring role as it turns out.

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?
