The hero trio find a lab full of apiculturalists (beekeepers to you and me) and before long we’re in not one but two bonkers bee B-movies, as one of the scientists, attempting to communicate with the bees, winds up pissing them off mightily, and then we discover the whole hive is being controlled by four giant telepathic mutant bees who are mind-controlling the leader of the project.

This really ought to be wonderfully insane, along the lines of one of the more balls-to-the-wall LEXX episodes or possibly a late 1970s Hammer movie, but this is The Starlost, so it’s curiously flat.
There are two good guest star performances (sadly there are four guest stars), and some really appallingly badly researched biology (the scientist who’s trying to communicate with the bees thinks they communicate by humming, for a start, and that’s before we get into the whole impossibility of giant bees), though there’s a nice shoutout to the then-ongoing Washoe experiment when one scientist observes that chimps are good at sign language.
Continuity: the hero trio are wearing brown velour jumpsuit or leisure-suit combos, like “Gallery of Fear”, with no real explanation why, or what they’ve done with their usual outfits. Once again the scientists know about the accident (which is firmly back 200 years in the past again), but don’t seem inclined to try and do anything about it.
