Crime strikes the vegetable world when Mrs. Mama Carrot awakens and finds her children have been carrot-napped. She summons the Irish-Potato Police and they are soon on the trail of the culprit. But the various suspects they round up, and grill, aren't the criminals. They finally track down the guilty parties, who turn out to be a gang of mice in disguise. Thrown into a third-degree mousetrap, the mice soon confess.
