When Richard Van Ness tries to ground dashing pilot Nick Talbot, his girlfriend's brother, from flying an unimportant cargo run in foul weather, he is blackmailed into allowing it because Nick threatens to tell airline boss Boyd Spencer about Van's intermittent blackouts. When Nick's plane apparently crashes near the Channel Islands, there are many nagging questions about the circumstances. Although he is innocent himself of wrongdoing, Van Ness is pressured by the police to aid them in uncovering some of the criminal activities associated with the operation, including blackmail, smuggling gold, and counterfeiting. In order to obtain the information he needs, Van Ness is forced into romancing Boyd's grasping girlfriend, who finds herself very attracted to the flier.
