Ghost Train presents several mystery narratives that are linked together, centering on Da Kyeong, a YouTuber whose feelings of envy and fixation slowly cause her sense of right and wrong to become unclear. Although the complex storytelling and numerous incidents occasionally prevent a more thorough examination of the reasons behind events, the movie consistently creates suspense through its mood, noteworthy acting, and realistic emotional fallout, instead of just using sudden frightening moments. Ultimately, it functions effectively as both a supernatural thriller and an analysis of aspiration and jealousy, creating a persistent feeling of discomfort.
