Now on Netflix, from writer/director Mark Dennis, it’s

Time Trap

Check out the ultra-informative synopsis from IMDB, lol:

A professor enters a cave and goes missing. Some of his students come looking for him and get trapped in the cave as well.

Wow. Could be anything, could be nothing…. could be a Time Trap!
