Blake's 7Avon decides to investigate something Servalan is investigating – a mysterious new source of energy on a distant planet. The sand-covered world is not what Tarrant and Dayna expect, nor is it expected that the sand itself is a vampire that feeds on all the unnecessary human males that arrive there, leaving any females and the strongest male as human breeding stock for future nourishment. And Tarrant becomes trapped there with Servalan.
