Mr. Dithers leaves Dagwood in charge of the office for a short period. Poor old Dagwood manages to gum things up when he falls for a confidence scam engineered by the duplicitous Toby Clifton. He even finds himself in a compromising position that seriously endangers his future connubial happiness with his wife Blondie. Once again, it's up to Blondie to straighten out the mess.
Blondie finds a valuable watch that has been hidden by hubby Dagwood. She assumes that it's a surprise wedding gift, but the truth is that Dagwood has been guarding the watch on behalf of a client who bought the gift for his own wife, which soon leads to trouble with his boss, a loan shark, and crooked building contractors.
Dagwood accidentally discovers a non-flammable paint. Bad guys Dillon and Stack steal it before he can give it to his boss Radcliffe. To show off his invention, Dagwood paints Radcliffe's house with it and is disgraced when the house burns down!
