Sir Geoffrey Radcliffe Vincent Price is sentenced to death for the murder of his brother Michael, a crime he did not commit. Dr. Frank Griffin, the brother of the original invisible man named John instead of Jack, injects the prisoner with an invisibility drug. As Radcliffes execution nears, he suddenly vanishes from his cell. Detective Sampson Cecil Kellaway from the Scotland Yard guesses the truth while Radcliffe searches for the real murderer before the drug causes him to go insane. The Radcliffe family owns a mining operation. The recently promoted employee Willie Spears Alan Napier is promoted within the company, stirring Radcliffes suspicions. After forcing Spears car off the road, Spears is scared into revealing that Richard Cobb Sir Cedric Hardwicke, Radcliffes cousin, is the murderer. After a confrontation, a chase scene ensues during which Radcliffe is struck by a bullet from Sampson. Cobb is killed falling from a coal wagon, but not before confessing to the murder. Radcliffe, dying from blood loss and exposure, makes his way to Dr. Griffin. A blood transfusion makes Radcliffe visible, allowing the doctor to operate and save his life. Vincent Price actually only appeared in the film for one minute, and spent the remainder of the movie as a disembodied voice.
