Saturday, 5:10 P.M. Sixteen-year-old Heidi Landseth is alone in her isolated home near New York City.

5:15 P.M. Across town, seventeen-year-old Patrick Farquhar, a volunteer rescue worker, longs to prove himself a real emergency.

5:41 P.M. A deafening roar fills the air and the sky glows red. Flight #116, a jumbo jet en route to New York, has crashed in the woods behind Heidi's house.

Mustering strength and courage she never knew she had, Heidi -- alone at first, and then with Patrick and hundreds of others -- works to help the suffering and dying victims. It is a night that will change her life.
