Kyle Pratt (Jodie Foster) is a propulsion engineer based out of Berlin, Germany. Her husband David died from falling off the roof of an avionic manufacturing building, and now Kyle and her six year-old daughter Julia (Marlene Lawston) are flying home to Long Island to bury him and stay with Kyle’s parents. They fly aboard a fictional Elgin E-474, which Kyle helped design. After falling asleep for a few hours, Kyle wakes to find that Julia is missing. After trying to remain calm at first, she begins to panic, and Captain Marcus Rich (Sean Bean) is forced to conduct a search. Kyle walks the aisles, questioning people, but none of her fellow passengers remembers having seen her daughter either. Shockingly, one of the flight attendants calls in to the airport they just departed from, and the gate attendant says that they have no record of Julia boarding the flight. In addition, according to the passenger manifest, Julia’s seat is registered empty. When Kyle checks for Julia’s boarding pass, it is missing.
Marcus refuses to allow the cargo hold to be searched because he is afraid that the searchers could be hurt if the plane shifted due to turbulence. Both Marcus and the other crew members suspect that Kyle has become unhinged by her husband’s recent death, and has imagined bringing her daughter aboard. Faced with the crew’s increasing skepticism regarding her daughter’s existence, Kyle becomes more and more desperate. Because of her increasingly erratic, panicked behavior, air marshal Gene Carson (Peter Sarsgaard) is ordered by Marcus to guard her.
Kyle, carrying Julia, exits via a cargo door. Everyone watches in shock and amazement as Kyle carries her daughter out onto the tarmac. In the passenger waiting section of the airport, Marcus apologizes to Kyle and leads her to a van which has come to take them the rest of their way. Julia wakes up and sleepily asks “Are we there yet?” The two get in the van and drive away.
