A few days ago I saw a post mentioning cannibalism, tunnels, and brain implant chips. It reminded me of a horror type flick I saw as a kid in the seventies or eighties that I don’t remember the name of but there were weird humanoid creature in a sandy desert area that lived underground and they would drag anyone caught outside underground to eat them. The law in the movie was that everyone had to be plugged in to some device into their head and it was illegal to be awake. This one girl woke up and went searching for her missing and presumed dead father and found out that he was the leader of the cannibals.

Any possibility of reality based?
