Carol likes her boss, but does not get involved with him as so many other secretaries would. She instead falls for a poor riveter and leaves to be married. She soon finds that the poor riveter is the son of Dan Kingdon and is loaded. When she gets her pretty ex-roommate a job as Bart's secretary, she now has to stand by her convictions as she "trusts" Diane. Aunt Agatha does not and tells Carol that she is foolish.
