Theo, an eight-year-old boy, insists 'I can save everyone' after his mother warns him not to joke. The episode opens on flight 8236, 800 miles from destination, on the nation's highest-altitude route where the crew can't operate the plane. Theo claims past-life flight experience and insists he can avert disaster. Air traffic control hears a child's voice; radar shows 8236 is out of control and entering the Dragon Snow Mountain area. Communication is lost. Authorities order all units to mobilize and activate the emergency plan, leaving Theo's proclamation unresolved as rescue efforts rush in.
