Park Ja-gi rejects everything his shaman mother taught him until his dreams start showing him the future, and by then he's already the only person who might stop it. A student who can freeze time, a teacher who sees catastrophe coming, and a school where the countdown has already started. The film doesn't ask whether these gifts are real or whether it matters, it only asks if knowing what's coming gives you enough time to change it.
A Seoul high school stands on the brink of tragedy. Park Ja-gi, a teacher haunted by prophetic nightmares, witnesses a horrifying vision: dozens of students lined up on the school roof, ready to jump. He refuses to rely on his shaman mother's spiritual guidance, but he can't ignore what his dreams are telling him. Something catastrophic is coming, and he has to act. Park isn't alone in his burden. Around the school, others carry strange abilities: a student who can freeze time mid-second, a man trapped in guilt who can rewind ten seconds but couldn't save his own family, and a girl who sees ten minutes into the future. These four misfits become an unlikely alliance, each ability a crucial piece of a puzzle they must solve before the apocalypse hits. Time becomes both their weapon and their prison. Every second counts. Every choice ripples forward or backward. Together, they race against an invisible clock to understand why their school is consuming itself and how to break the cycle before it's too late.
