When Flight 702 vanishes from radar without a trace, data analyst Adaobi discovers a faint reversed echo in the flight feed that leads her to an abandoned industrial zone. There she learns the plane did not crash but passed through a hidden dimensional veil into a mirror layer of reality. The passengers return changed, unified by a collective consciousness that observes humanity. As the boundary weakens, the mirror beings attempt to cross over, offering unity at the cost of individuality. Realizing the veil responds to frequency, Adaobi uses a reversed radar signal to force it closed. The world accepts a false crash narrative, but Adaobi knows they are being watched, and the next opening may not be accidental.
