When an innocent boxer (Arthur Franz) is set up and charged for killing his manager, he takes a serum to make himself invisible and escape the police.
A couple of bumbling private investigators (guess who!) step into the ring to try to add visibility to the situation.
There is a modicum of mystery beneath the thin layer of comedy, and the highlight is a boxing bout in which Bud gets an invisible hand to hold off the champ.
The film features convincing special effects by John Fulton, the camera ace who also did trick photography for the original Invisible Man.
