Pete Nessip (Snipes) and his brother are U.S. marshals escorting convicted computer hacker Earl Leedy to a federal prison on a commercial 747.

An apparent terrorist attack results in an on-board explosion, the death of Pete's brother and Leedy's disappearance.

In the aftermath, Pete's badge is suspended while authorities investigate the accident.

Determined to track down his brother's killers and locate Leedy, Nessip is drawn into the daredevil world of exhibition skydiving.
