Flying Blind was the third of William Pine and William Thomas' independent productions for Paramount release. The cast includes such Pine-Thomas "regulars" as Richard Arlen and Jean Parker, and like its two predecessors dealt with the more dramatic aspects of aviation. Arlen plays Jim Clark, operator of a honeymoon air service which shuttles between Los Angeles and Las Vegas. The plot shifts into melodramatic gear when Clark is forced to deal with a gang of foreign spies, determined to steal a new transformer designed for American fighter planes. A wild and largely impossible airborne chase brings this one to a rousing conclusion. For the record, Jean Parker plays Clark's secretary Shirley Brooks, who not-so-secretly hopes that her boss will fly her to Vegas for matrimonial purposes.
