Abbott & Costello Meet The Invisible Man
Champion boxer Tommy Nelson is accused of killing his manager after a fight. To hide from the police until he can find the real killer, Tommy injects himself with an invisibility formula. Dr. Grey warns him that the formula could drive him mad if he stays invisible for too long. He then goes to two detectives, Bud Alexander and Lou Francis, to help investigate the murder. By getting Lou in the boxing ring with invisible Tommy's help, they try to expose gangster Morgan as the real killer.
