Lou Francis (Lou Costello) and Bud Alexander (Bud Abbott) graduate from a private detective class. They are hired by boxer Tommy Nelson to visit his girlfriend Helen Gray and her uncle Dr. Philip Gray. Despite Lou's suspicions, Bud doesn't realize that Tommy is an escaped prisoner convicted of murdering his manager. Tommy needs to prove his innocence and uses Dr. Gray's dangerous invisibility serum. Lou witnesses Tommy turning invisible but nobody believes him. Helen hires the boys to help Tommy.
Lou is great although Bud does need to be clearer in his positions. I'm not always sure how much he is clued into the situation especially early on. Of course, he's the straight man but he could be more charismatic. I'm more of a Laurel and Hardy fan. The best invisible gag is probably the spaghetti. The best non-invisible gag is hypnosis. Some of it is pretty fun. The boxing has some funny gags although it's funnier when Tommy isn't there. Lou getting punched is hilarious. This movie has plenty good fun gags.
