A fire suddenly broke out at Rainbow Bridge Kindergarten. The teacher Sierra desperately carried thirty children out of the flames, but she herself was struck and suffered crippling injuries to both legs. Yet what awaited her was not gratitude — all the children had died, and her fingerprints were even "found" on the fuse box. Her colleague Chloe tearfully testified that Sierra had locked the children inside, and her husband Ethan produced her medical records of three miscarriages,
falsely accusing her of hating children and setting the fire. Abandoned by everyone, Sierra was
stabbed to death by an out-of-control parent.
When she opened her eyes again, she had returned to the day of the fire. In this life, she was
well prepared: she smashed open the emergency exit that had been deliberately blocked,
transferred all thirty children, entrusted them to her confidante Nora, and hid them in a passage, while she alone remained in the classroom, quietly waiting for those who had framed her to walk into the trap themselves. When everyone insisted the children were dead and rushed to convict her, the children reappeared completely unharmed.
With that, the lie collapsed. Sierra seized upon the contradictions in the testimonies, pulled out
the fingerprint transfer film from Ethan's bag, and, together with the surveillance footage, the
911 recording, and the fingerprints on the fuse box, uncovered the truth layer by layer - Chloe
was actually the biological daughter of the kindergarten principal Diane. To stop Sierra from
taking over as the person in charge, the mother and daughter did not hesitate to set the fire,
using the lives of thirty innocent children as bargaining chips, while Ethan was an accomplice
who had been having an affair with Chloe. The three were ultimately severely punished by the
law. Sierra ended her marriage, started over by founding a new childcare center, and took a new step forward in response to the kindness of Officer Noah.
