Best friends Annie and Sarah need cash - fast. Sarah, a beautiful, successful lawyer, wants nothing more than to have a baby. But balancing IVF treatments with a grueling eighty-hour workweek is no walk in the park. Meanwhile, Annie, a Harvard-grad chemist recently transplanted to Southern California, is cutting coupons to afford her young autistic son's expensive therapy.

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, Ben too becomes suspicious. Who left the postcard behind, which flight is that person on, and what exactly does the message mean?
