The premise sounds like body horror setup. It's actually about a woman watching her entire self dissolve the moment she becomes a mother, and the film doesn't flinch from how claustrophobic that feels. Sehyeon isn't fighting a supernatural force, she's fighting the biological reality that her body has stopped belonging to her, that her ambitions now have a weight literally pulling her down. The horror isn't what emerges from her; it's what she has to become. This is the film that puts a climber at the summit and shows you the exact moment she realizes she's never going back up, pregnant or not.

Choi Se-hyeon is a professional climber who has only recently recovered from a car accident. Just before the Climbing World Championships, she discovers she is pregnant. With the goal she has pursued for years suddenly at risk, she fights to free herself from the demands of motherhood, yet the baby will not let her go. At the same time, text messages begin arriving from another version of herself, one who seems to have lived a very different life after the accident. Torn between ambition and the child she also wants to keep, Se-hyeon faces a feature-length ordeal of psychological horror.
