Devon (Keir Dullea), Garth (Robin Ward) & Rachel (Gay Rowan) encounter Omocron - a community run as a theocratic military junta and Rachel is mistaken for their goddess 'Calabra'. The governor (John Colicos) of the junta and its high priest (Barry Morse) think that religion is hooey but play along with it to maintain power.
Being a society replenished via male-only test tube babies Rachel is the first woman any in Omocron have seen beyond their statue of Calabra which Rachel bears a striking resemblance to. The governor decides he wants her. Marrying her won't just provide him with female companionship. To wed her will make him a living god and he won't continually have to fight in duels to maintain his rule.
The governor is unconcerned about what Rachel says regarding the fact that they are on a giant spaceship or her mission to alter the course of the ship so that it doesn't collide with a sun. His teachings are that Omocron is the only world there is when it is really merely a colony within one of several biospheres.
Devon wants to examine the ancient scrolls of Omocron in hopes of figuring out how to navigate the Ark. But he and Garth also want to save Rachel from marriage to the creepy old dude.
John Colicos had played a Klingon on Star Trek and would go on to play Baltar on the original Battlestar Galactica (1978–1979) as well as act in TV sci-fi War of the Worlds (1989).
Barry Morse had appeared on the sci-fi series The Invaders (1967–1968) and would go on to act in Space: 1999 (1975–1977) and The Martian Chronicles (1980). With Keir Dullea - the lead of 2001: A Space Odyssey (1968) as star of the show this episode had a cast with immense resonance amongst science fiction fans.
Of course shot on video on a set that looked like a miniature golf course made from legos meant that the high-grade cast could not be of much help. Many of the guest-stars were hired believing the show would be a considerably more impressive spectacle than they found themselves appearing in. Viewing the dailies must have been an utterly horrific experience for everyone.
The slipshod costuming in this particular episode looks like the kind found in discount stores for kids to go Halloweening mixed with old pajama bottoms and metallic lame shirts.
The props mostly look like stuff you would find in a toy store. We get the typical depiction of computerized instrumentation that the screen gave science fiction audiences of the time. Boxes with lots of flashing lights, phony levers and gauges that only look like they are doing something.
The strength of the series remained the writing and the theme explored in this episode - men who suppress knowledge via religious dogma in order to maintain power over the ignorant was a recurring topic on the show.
