ACCIDENTAL HEROES

On a beautiful May morning at New York's John F. Kennedy airport, two planes have just departed for San Francisco -- one a 757, another a smaller Airbus A321. At a security checkpoint, TSA agent Bernice Adams finds a postcard of the Golden Gate Bridge bearing an ambiguous -- perhaps ominous -- message. Her supervisor dismisses her concerns, but Bernice calls security and soon Ben Waterman arrives. A senior Homeland Security agent, still grappling with guilt after a disastrous operation in which hostages were killed, Ben too becomes suspicious. Who left the postcard behind, which flight is that person on, and what exactly does the message mean? As Ben scans the passenger manifests, his focus turns to the A321, with Helen Smith as its senior pilot. Helen's military service and her tenure with the airline have been exemplary. But her husband's savage death in Iraq was more than anyone should bear, leaving her widowed with three children. A major film star is on board. So is an off-duty pilot who has just lost his forty-year career. So is a distraught father, traveling with the baby son he has abducted from his estranged wife. Sifting through data and relying on instinct, Ben becomes convinced that someone on Helen's plane is planning something terrible. And he's right. As the jet bears down on its destination, strangers are united, desperate choices are made, and futures will be changed forever by a handful of accidental heroes.
