One year after James - a brutal, sadistic hitman - and his accomplices viciously murder Amanda - a young flight attendant - onboard a Rising Airways jumbo jet, they inadvertently step onboard the same plane to find themselves at the mercy of Amanda's vengeful ghost. Told in flashback, The Flight Attendant is a story in which we incrementally absorb the lives of the people onboard the plane - lives that include an explosive event in Vietnam, a childhood gone terribly awry in Chicago, and a heart-breaking good-bye in California. Lastly - and inevitably - we discover what happens when the ghost of an iron-willed flight attendant is hell-bent on getting her revenge against a die-hard killer.
