The story is mainly about people running up and down hallways and stairs. I hope they got paid double for all their huffing and puffing. Oh yeah, there's also something about an invisible man in a diving helmet and pajamas. From the way he breathes, he ought to have his adenoids checked. I think he's from outer space, but more likely he's a diving school flunk-out. What can you say about a cheap snoozer like this with its no-name cast. Heck, there isn't even a sexy girl to keep us guys in the back row entertained. Between all the pseudo-scientific palaver and the sprinting back and forth, there's not much left to look at. My guess is it played one or two drive-ins farthest from town, and then disappeared like the phantom in the movie.
