Meteorologist Leah Kaplan (Daryl Hannah) and her team of
National Storm Center (NSC) scientists set out from
Jacksonville, Florida on a routine tracking mission to gather data on Hurricane Josephine, forming up over the Atlantic Ocean. Along with Leah, technician Tommy Cramer (Terry Chen) and meteorologist Steve Pastor (Sean Bell) have been joined by a reporter, Ryan Stewart (Dylan Neal) gathering information on a feature article on the hurricane hunters. Both Leah and Tommy worry that Steve, recently
furloughed because of a drinking problem, will be unreliable. Ryan also is an unnecessary complication to the flight as he continually probes for details about the mission and Leah's background and motivation. Leah reports back to her supervisor Eli Harder (William MacDonald) who is involved with a full-scale evacuation of
Corpus Christi, Texas called by NSC Director James McCaffee (Mackenzie Gray), due to the proximity of
Hurricane Ike. As Hurricane Hunters Flight 263 enters the hurricane outer wall at 1,500 ft where the winds and turbulence are at their greatest intensity, the data that is being returned from the launching of
dropsondes indicates that the hurricane is gathering strength. Relaying the message back to headquarters does not bring an immediate response as the Director worries that Leah's past background in losing her parents in
Hurricane Edna has clouded her judgment, a concern that Leah's psychiatrist Dr. Johnson (Gwynyth Walsh) has been exploring. The sudden pitching and turbulence pitches Steve headfirst into his control console, precipitating a fatal heart attack. For a brief period in the
eye of the hurricane, Leah, Ryan and Tommy are able to deal with Steve's death. Leah again tries to alert the NSC that Hurricane Josephine has shifted and is headed directly to Jacksonville. Announcing a second evacuation is problematic, the NSC Director, despite Eli's pleas to look at the data Leah is sending, refuses to change the evacuation plans already in progress. The violent storm suddenly turns into a level 5 hurricane with winds at over battering Flight 263. Captain Henry Gersh (Barclay Hope) and co-pilot Ben Tillner (Chad Cole) on his first hurricane hunters flight, wrestle the aircraft through a climb that abruptly turns into an out-of-control dive to wavetop heights. After a fire in one of the engines is doused by the violent rain storm outside, electrical systems begin shorting out, with both Henry and Tommy blinded by the sparking equipment. Leah is abruptly hurled into the ceiling as the aircraft enters a
parabolic maneuver. Turbulence increases with the rear exit door torn off, and the sudden
depressurization sucks both Leah and Tommy out of the aircraft. Caught in the cargo netting, Leah is still alive but badly hurt. Ryan reacts quickly to haul Leah back inside, with the two crawling their way to the cockpit for safety. Leah has a dislocated shoulder that Ryan attempts to reset but with Henry blinded, she convinces Ryan that he has to help Ben fly the crippled aircraft. Receiving Flight 263's
mayday distress message and on the ground reports of the hurricane already battering the coast, Eli finally convinces the Director that Hurricane Josephine is the greater danger. Ben and Ryan manage to bring the aircraft down safely at Jacksonville, and as Henry and Leah are brought out by emergency crews, all the surviving members of the flight find out that their loved ones are safe. ==Cast==
