Murat Bernard "Chic" Young was an American cartoonist who created the comic strip Blondie.
Dagwood inadvertently gets cornered in to resigning. When his wife Blondie tries to ask Dagwoods boss Mr. Dithers for his job back, he ends up hiring her instead. This doesn't sit too well with Dagwood. Blondie's sister comes to visit, and Dagwood is put in a compromising situation with another woman.
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.
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.
