A convicted murderer is escorted by marshals on a regular flight from Phoenix to Dallas. Shortly after takeoff, two of his aides, traveling as ordinary passengers, take control and free him. He demands $20 million in bonds upon landing. And a sick passenger, bad weather or mechanical problems won't stop him.

Movie based on the true story of Helen Keller, now an adult, and her teacher, Annie Sullivan. Their close relationship is threatened when John Macy, a caring young professor at the college Helen attends, comes between them. John and Annie fall in love and marry and the two women must choose what is more important — the love between a man and woman or the bond between the two of them.
