The hero trio find a biosphere governed by a queen who is in thrall to a vizier, who controls the population by means of a brain implant that’s supposed to enhance mental capacity but can also be used to cause immense pain. There’s not much to do bar mount a resistance movement and depose him, though of course he does the usual villainy things like holding Rachel hostage and explaining his plans at length to anyone who’ll listen.
Other highlights include the biosphere’s council forming a resistance cell literally minutes after the vizier dissolves the council and reveals himself (hahaha!!!) as the villain, and the fact that the implants themselves are almost entirely irrelevant to the plot (you could substitute any pain-giving magical object to the same effect), and are also wasted as a plot device. There’s also a child; the saying is that when a series starts doing episodes with children, it’s on shaky ground, but this one started off there so it doesn’t change much.
No entertaining guest stars from Canadian comedy or telefantasy either, more’s the pity, though they seem to have spent some of the costume and set budget.
This is possibly my top candidate for worst episode of the series, because it’s not just awful, it’s awful in a very boring way.
