Park Jagi has always had the gift of foreseeing impending disasters in her life. However, she has never been able to prevent them from happening. That is, until now. Her latest premonition reveals an impending tragedy at her school, and within the vision, Jagi sees herself along with three strangers who can help her stop it. With only a few days before the disaster is set to occur, Jagi races to find her potential allies.
Upon meeting them, she discovers that they, too, possess unique abilities related to time. Kim Young-Tak can freeze time, Chang Sae-Yoon sees events ten minutes before they happen due to her narcolepsy, and Kang Min-Hyuk can rewind time by ten seconds. But just as Jagi tries to convince them to join her cause, tragedy strikes the school unexpectedly. To make matters worse, the timeline has shifted, and events are happening sooner than anticipated. Jagi begins to question her powers and how they could have misled her.
