Producer/director William A. Wellman also co-scripted this biopic devoted to John J. Montgomery (Glenn Ford), the unsung 19th-century innovator of glider design. Montgomery's invention of a gold separator proves lucrative, but he pours its profits into financing his legal battles over patent infringement. The gliders created by Montgomery attract attention but no money, and he begins a relationship with Regina Cleary (Janet Blair), which helps sustain him. But when Montgomery becomes afflicted with vertigo and can no longer fly, he sickens and dies. ~ Nicole Gagne, Rovi
