When the title of this movie was first called "Alone in the Dark," I thought the main character was suffering alone, but I didn't dare think that the majority of 33 people would be the main character, so I was very curious about what the movie was about. The first start is August 5th, seeing everything shattered by the explosion and the miners trapped underground, I was curious to see what would happen. When I watched the movie, I thought that the reason why the majority of 33 people survived was because everyone was united with the desire to live. This unity created discipline and rules, and became the last hope of the miners.Seventeen days after being trapped in an underground cave, a small hole was created in the underground cave. I thought the miners could finally escape. However, the rescue was not easy because it was trapped in such a deep underground cave. Many things happened and eventually, 69 days after being trapped in the cellar, rescue operations began on October 9, and finally all the miners were rescued on October 13. I was relieved, and I really admired the 33 miners after I found out that this movie made a movie of what really happened. Also, I realized that life is very precious through this movie
