Joe Mannix is about to go on a golf date with his friend Pete Pinelli, a helicopter traffic reporter for a local radio station, when he receives word that Pinelli's copter has crashed in a remote area of Los Angeles County. Mannix uncovers a witness who saw a light plane in the area just before the crash, and becomes convinced that Pinelli was murdered because he saw something that he wasn't supposed to see -- a conclusion that's bolstered when the pilot of the light plane appears to have been murdered as well.
