Pete Nessip is a Federal Marshall who, teamed with his brother Terry, is escorting criminal computer genius Earl Leedy to a new prison facility. Pete, Terry and Earl are on a jet en route to Earl's new lockup when terrorists attempt a daring hijacking. Terry is killed in an explosion aboard the plane, and suddenly Earl is missing. Pete discovers that a team of sky-diving outlaws, led by former DEA agent gone bad Ty Moncrief, have snatched Earl from his flight and spirited him away for a special raid on Washington D.C. Ty and his men intend to take advantage of an obscure rule in which the normally restricted airspace in Washington D.C. is open to parachute enthusiasts on July 4. Eager to avenge his brother's death and put both Ty and Earl behind bars, Pete recruits sky-diving expert Jessie Crossman to teach him how to infiltrate Ty's team of sky-bound criminals.
