On a flight suddenly forced into emergency procedures, passengers are ordered to sit as a countdown ticks toward autopilot. The narrator is seated at the emergency exit, 11A, and tells her father this is the safest evacuation spot. She flashes back to her parents' breakup—Brianna leaving after divorce—then remembers a past-life crash where her father shielded her and she survived. Now, with a second chance, she vows to protect him and everyone on board. Autopilot engages and her vow becomes an urgent order to act before fate repeats.
