I am desperate to start doing these. Find a bunch of Non Trek fans and just give them the most off the wall, insane, ridiculous no context screenshot and have them try to explain.
Jokey answer: recess but they have access to deadly weaponry and only the strongest will make it to maths class.
Serious answer: I presume this is some kind of proof-by-combat scenario? A local culture demands the protagonists fight one of their own in some cactus-pugilism jungle-gym arena in order to prove their worth, and only then will they grant them whatever boon they asked of these people?
Ok I followed your instructions to a T.
It looks to be like a combination of Ru Paul's Drag Race (and I mean this in the best way possible) and a professional game of parkour chase tag.
Was I close? I'd love to know what's actually happening!
Edit: OK I read some comments and it's a battle for life and death. Fuck me.
Though, I've only missed... Uhhhh... Okay I've only seen TNG, Voyager, DS9, and Enterprise. And Online. And a season of Discovery. ... Which I kinda regret.
Well, come on then! What's the story in the screenshot :P My very shallow awareness of TOS suggests it may well be #1, but could also be #3, which is hilarious to think of but less funny if that's actually what's going on 😅
I vaguely remember that they were being held captive and the devices would punish them for misbehaving. Like, some guy lived with a bunch of female robot slaves or something and the episode ended with him having to live with a robot version of his deceased henpecking wife? Shit I don't know, it's been like 30 years since I watched the original series...
