It makes you dread a school rooftop. Park Ja-gi spends his whole life shoving his shaman mother's world away, and the film's cruelest joke is that the gift keeps showing up anyway, in dreams where a line of people wait their turn to step off the top of the building. Kang Full's premise gives these characters powers that sound like superhero material and then makes them almost useless: Kim Yeong-tak can freeze time and still cannot fix what a person has already decided about themselves. That gap between seeing the catastrophe and being able to stop it is where the whole thing lives, and it hurts. This is a Korean animated thriller that treats teen suicide as a real emergency rather than a plot engine, so it lands heavier than the mystery framing warns you. You will finish it thinking about who you did not call back.

A Seoul high school is shaken by a string of suicides, and this mystery thriller sets out to uncover what lies behind them. Park Ja-gi, a teacher there whose mother is a shaman, rejects anything mystical, yet his dreams show him disaster before it happens. In one vision he sees a crowd of people poised to leap from the top of the school building, and he resolves to stop the mass suicide. He is not the only one with an unusual gift. Kim Yeong-tak, a student, can bring time to a halt. Kang Min-hyeok can turn time back ten seconds, though he carries guilt over failing to save his wife and child. Jang Se-yun can see ten minutes ahead. Together they combine their powers to head off the catastrophe at the school.
