Dagwood Bumstead must receive a college diploma or lose his job with the Dithers Construction Company. Not wishing to be separated from her husband, Blondie enrolls in college as well. But Leighton College rules stipulate "No Married Couples", forcing Blondie and Dagwood to pretend that they're not married. This causes quite a dilemma when coed Laura Wadsworth begins flirting with Dagwood and Rusty Bryant does the same with Blondie. And Blondie's discovery of a very pleasant secret threatens to expose her and Dagwood's marital status too.
