Kate Parks has spent the past year on tour promoting her book, an in-depth look at the attempted cover-up of her husband's death in a plane crash. Now all she wants is to return home to her daughter, 15-year-old Samantha. But when a powerful solar flare strikes her flight home, killing the pilot, knocking out the co-pilot and frying all the electronic systems on the plane, it looks like she may not get there. As she panics, can she land the plane safely and see her daughter again.
