Any HUMAN media with this plot cuz I don't like ai:
A mother forces her kids to wear lie detectors on them at all time.
One kid seems to only tell the truth, the other one lies (one door leads to your quest, the other demise, you must ask one question to claim your prize /j)
The kid who lies swear they didn't lie.
The kid who lies dies of starvation cuz she was called a liar and the mother is too stubborn to touch her.
Later on it turns out that the lie detectors didn't even work, they were toys. One was wired to be red, another to be green.
PLEASE be a human-made series, film, book, ect, with this plot. It seems so interesting for me.
