A party of tourists -- including a state senator, a park ranger who was her one-time lover, a cantankerous professor, and an escaped convict -- are trapped deep inside the caverns of an unnamed national park, rescued briefly, and then caught in a second cave-in.
Unfortunately the movie Cave-In! is not yet available on Disney Plus.
