Blondie and Dagwood are about to celebrate their fifth wedding anniversary but this happy occasion is marred when the bumbling Dagwood gets himself involved in a scheme that is promising financial ruin for the Bumstead family.

Things get under way when Blondie Bumstead demands that her husband request a raise from his boss Mr. Dithers, so that she can afford to hire a maid. But Dithers has no time for any salary disputes: his construction firm is currently stuck with an unsaleable old mansion that is rumored to be haunted. To disprove this theory, Dithers ...

The Bumstead family is off to see relatives in the country when Blondie runs into Charlie and Millie, an eloping couple needing her help.

Mr. Dithers invites the Bumsteads on a South American cruise. Somehow Dagwood winds up as the female drummer in the ship's band, while Penny Singleton gets to show off her Broadway background in some lively musical numbers.

Dagwood Bumstead, intending to buy a house, buys a horse instead. However, Dagwood quickly gets mixed up in a fox hunt, and Blondie must save the day.
