Anne is a pilot for an airline plagued by labor disputes, financial problems, and lawsuits. But it pays enough for Anne to raise her daughter after a bitter divorce from her emotionally unstable and violent ex-husband, Cal. When Cal escapes from an asylum, he puts his plan for revenge into action--29,000 feet above the ground.
