Beware of Blondie (1950)

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.
