The Man Who Found Himself on AllMovie

A doctor (John Beal) who loses faith in his skills renounces his profession and hides himself in a variety of jobs. He takes a minor job at an airfield, where he meets nurse Joan Fontaine, who works on a "flying hospital". On board the aircraft, Beal finds he is the only person who can perform a delicate operation; worse luck, the plane is about to crash! Beal finds himself, per the title, but nearly loses his life in the process. Watch for Dwight Frye, the immortal "Renfield" in Bela Lugosi's Dracula, as an hysterical patient--and seven-year-old Dwight Frye Jr. as a child rescued from a train wreck.
