In "Hold That Woman!" you hear the term 'skip-tracer' a lot and because it's such a seldom used term, it would be best if I explain it before getting to the review. Like the words say, this is a person that looks for someone who has skipped out of town and is in hiding. The skip-tracer can be doing this for a variety of reasons, such as bounty hunting, process serving (court notices) and, in the case of this movie, it's someone who is looking to repossess items for which the owners did not finish making payments. Making such a person the hero in your story is a bit odd to say the least.
The skip-tracer in this film is Jimmy Parker (James Dunn). When out collecting a radio from a very unpleasant woman, he gets himself into trouble by breaking into her apartment. Sure, she's a crook but legally you cannot just break in to repossess the radio. The lady is very indignant and insists on pressing charges against him. But this is a ruse...she doesn't want him to have the radio because there is something hidden inside and she cannot let him have it. What is it and who else is looking for the radio?
This film was made by tiny little PRC Studio--one of the crappier small-time outfits of the day. Most of their films are very forgettable--with lousy stories, directing and acting. Here, however, PRC actually created, accidentally, a decent movie which still contained a few of the usual clichés (such as the leading guy who knows MUCH more than the dopey cops). Overall, this is a mildly entertaining mystery movie--with both a bit of comedy and some gritty violence (I like the drill sequence).
