Reading the accident report in American Caving Accidents, one reads that there were about 12 people there, and many left before the incident. The story is a little slow, and based on a true story. If all of the shown scenes are factual, then I learned a little more than before. There are some Mormon doctrines that are shown, which you can discount if necessary. It's always sad to see a story where you know the ending. It's like watching the Titanic.
This movie is chringe worth at best, and sometimes much worse... It's funded by the Morman church, and used to try to convince us that the afterlife is more important than anything else! Garbage and a horrible film. I can't believe I watched the entire thing.
