Query: Flightplan

Kyle Pratt is a frantic but fiercely intelligent mother whose deepest protective instincts will be triggered by a haunting in-flight nightmare: in the middle of the trans-Atlantic trip, her young daughter turns up missing without a trace. Or does she? Kyle arrives on the flight still reeling from the recent loss of her husband, a woman who has gone mad with grief or a formidably determined mother whose child is in grave danger that threatens the entire plane. This movie is a frightening thriller with an airtight plot and it's a tense, concise and elegantly movie that creates a sense of menace from the very beginning in a way that's unusual.
