Plot

Dagwood purchases the wrong real estate property and Mr. Dithers promptly demotes him to office boy. Dagwood's substitute is sent to deliver blueprints to the estate home of a wealthy client, Mr. Dixon, and gets into a fistfight with Dixon's unwanted son-in-law. The delighted Dixon mistakenly thinks the substitute was Dagwood, and asks Dagwood for a personal boxing lesson, as a pleased Mr. Dithers restores Dagwood to his former position. Meanwhile, two swindlers come to the Bumstead's house to have him sign over a deed to what Dagwood doesn't realize is a valuable property. Alexander and his friend had overheard the swindlers plotting, and they try to interrupt the transaction, but are shooed away and have to take comical measures to stop the signing.
