A girl returns to the heavy rain night many years ago, twenty-eight minutes away from her mother facing danger. She struggles to persuade her father to go find her mother immediately, guiding the route with her memory, and arriving at the scene before the incident occurs. Facing the disguised and kind neighbor, she calmly states the other person's whereabouts, punctures the other person's excuses, timely prevents the danger from happening, guards her own family, and rewrites the tragic fate of the whole family.
