There was a similar theme in an episode of Star Trek the Next Generation [1]. They visited what appeared to be a utopian planet with everyone dressed in skimpy outfits, landscape was beautiful, people were super friendly. The ships chief medical officers son Wesley tripped over a small fence around a garden after convincing other teenagers to play catch and guards showed up to euthanize him for breaking the rules.
