Stan and Ollie have been working for a circus, but the circus is now closed for business. The circus owner does not have the cash to pay the pair, so they are given a flea circus and a chimp as payment. The chimp’s name is Ethel and she is trained to behave as she is told to. The only problem is that the landlord, who lives in the same building as Stan and Ollie, has a wife with the same name as the chimp. A series of comical incidents makes the landlord think that something is fishy, as if it was not bad enough that he is already the jealous type.
