Cally begins sabotaging the Liberator and attacks Vila. Blake and Avon rush to stop her as the sensors go inoperative and it rapidly becomes apparent that Cally is not in control of her actions. The Liberator enters a huge, spaceborne web that slows the ship down and brings it to a planet inside the web. Blake teleports down and is injured by a tiny creature’s spear. A couple of humanoid beings appear, kill the animal, and miraculously heal Blake’s wound. It transpires that the animals – ten-function, artificial slaves callled the Decimas – were created by Geela and Novara, who are under the control of Saymon – whose telepathic impulses had been controlling Cally – and the Decimas have now become independent and their creators are attempting to destroy them. They leave Blake no choice: they demand power cells in exchange for the release of the Liberator. But as Avon arrives with the cells, the Decimas attack the control building, killing their creators. Blake and Avon return to the Liberator as the web dissolves.
