Broadcast on 11 November, 1976, Seed of Destruction, penned by John Goldsmith lets Commander John Koenig (Martin Landau) indulge into that classic sci-fi trope, the evil twin.
He and Carter (Nick Tate) are investigating a strange asteroid that Maya (Catherine Schell) reports is giving off a strange energy reading. While Carter works on the Eagle, Koenig explores a cave where he is rendered unconscious by a race known as the Kalthons and replaced by a duplicate who takes over Alpha, sequestering the science divisions, and taking charge in his own way.
On the asteroid Koenig leans the truth of the Kalthons, and what they are looking for, their entire civilization is held in a seed, a seed that will draw the energy it needs from all of Alpha, machine and man.
Tony (Tony Arnholt), Maya, Carter, and Helena (Barbara Bain) suspect from the off that there is something wrong with Koenig, and try to work around him, investigating the strange rock/seed that the commander brought back to Alpha with him.
Will they confront him? Will Koenig escape from the asteroid? Will they find a way to restore the Kalthons? – Well maybe not that last one… this species seems really cruel, considering the lengths to which they plan to go to save only themselves, and the rest of the universe be damned.
The Alphans risk all to try to stop duplicate Koenig, and lives are laid on the line, as they desperately try to outmaneuver the impostor.
The AB Chrysalis was written by Tony Barwick and first aired on 18 November, 1976. The moon draws close to a strange planet that appears to be populated by robots. But Koenig and the rest learn that the humanoid beings who live here enter a pupal stage and when they emerge they have heightened physical and mental abilities, near perfection.
The robots see the arriving Alphans as a threat and plan to be rid of them, but the final decision will rest with two of the newly restored humanoids who have emerged from their chrysalis one of whom is Sarah Douglas!
I’m going to use a brief aside to talk about the wonderful 70s sounding score to the second series, lots of bass guitar, and swinging beats that just don’t really do the series any good, but damn if they aren’t fun to listen to.
As of this episode the moon is 1288 days out of Earth orbit, and the journey will continue for another twelve episodes, so come back next week for more British science fiction adventure (featuring awesome model work, rocking sounds, a solid cast, and some iffy stories) and join me for Space: 1999!
