In this chiller based on true events, a jetliner crashes in the Florida Everglades, killing more than 100 passengers along with the flight officer, Dom Cimoli (Ernest Borgnine). When engineers use pieces of the damaged plane to repair other jetliners, crew members and passengers experience haunting visions of the dead flight officer. While Cimoli's ghost seems terrifying at first, each crew eventually realizes that the spirit is warning them of impending disasters.
