When innocent boxer Tommy Nelson (Arthur Franz) is set up and charged for killing his manager, he steals a serum from Dr Philip Gray (Gavin Muir) to make himself invisible and escape the police.
A couple of bumbling private investigators (guess who) who have only recently graduated from Dugan’s Detective Academy step into the ring to try to add visibility to the situation.
The plan to clear Nelson’s name involves Lou pretending to be boxer Louie the Looper, stepping into the ring with Rocky Hanlon (John Day). Unknown to the gangsters who have a lot of dough riding on the bout, it’s really a handicapped match with the invisible Nelson ensuring a victory for the Looper.
Lou eventually somehow gets the invisibility serum into his own bloodstream, resulting in some brief silliness in a hospital ward.
The film features convincing special effects by John Fulton, the camera ace who also did trick photography for the original Invisible Man.
