Tom is listening to a spook story on the radio (a form of entertainment I wish was still around) and is so wound up by the possibility of ghosts, that he jumps in fright at every sound. Taking advantage of this for his own personal fun, Jerry tries to freak Tom out by playing pranks on him, the main one being sticking a white sheet on a vacuum cleaner and pretending it's a ghosts. Obviously Tom becomes aware of Jerry's cruel tricks in the end.
It's very mildly funny though nothing really spectacular happens. I can really only recommend this to very young children as there is no real intelligence or wit to entertain an adult. Tom still looks a little rough, as he did in the early stages of his characters animation. Mammy-two-shoes shows up, but on the version I saw she was dubbed to make her sound more PC, as was common with Tom and Jerry cartoon manipulation in the early 90s.
