Global Airways domestic flight 502 to Minneapolis-St. Paul has the potential for issues when Angie Thatcher, the girlfriend of co-pilot Sam Allen, is reassigned as lead flight attendant, those issues as she is also the ex-girlfriend of the pilot, Hank O'Hara. There is further excitement once in the air as the President of the United States relays a message for one of the passengers. But those two issues take a back seat when a note for one person obviously to find states that there is a bomb aboard the plane and the note writer will detonate said bomb unless the flight is diverted to Anchorage, Alaska. The location of the note means that it had to have been written by one of the passengers in first class: a jazz cellist off to a gig; an army sergeant on furlough to attend his sister's wedding; a US Senator and his young adult son off on a fishing trip together; a young female hippie; a pregnant woman nearing the end of her third trimester, she traveling without her husband; and a couple past middle age on their latest move due to yet another work transfer, which the husband views as "losing". The flight crew has to view everyone as a suspect in taking whatever each says with a grain of salt. But even if they are able to discover the identity of the hijacker and his/her motivation and end goal, they still have to find and defuse the bomb.
