Mr. Peepers' sister Agnes arrives with a young scientist colleague from Chicago to view an eclipse of the sun which can only be fully observed in Jefferson City. Mom Peepers phones her son, asking him to carefully appraise Agnes' boyfriend, since she is not sure that he is right for Agnes. Peepers tries to watch both the boyfriend and the eclipse together.

When Mrs. Gurney and the Weskits discover the inadequacies of the Peepers' makeshift furniture, they plan a "furniture party" for Robinson and Nancy. It is Mrs. Gurney's duty to see that the Peepers remain at home that evening, but when they go off to the movies instead, it becomes Wes' job to go retrieve them.
