Bill, Jane, Jim, and Jack, four aspiring young pilots, enroll in flight school and are assigned to John Woodward, a tough but sympathetic flight instructor. Bill hopes to become a commercial pilot, Jane, his fiancee, an instructor, and Jim, an army pilot. Jack's brashness and lack of discipline cause him to get cashiered as a pilot, but to his credit he re-enrolls in order to become an aeronautical engineer.
