Reporter Jimmy Munroe is writing an article on "the average woman". He meets Sally Whipple in the library and chooses her as a likely subject, following her around to gather material for his article, and eventually falls in love with her. Her father, Judge Whipple, doesn't like it; he has Jimmy arrested and allows him to see Sally only once a week. Meanwhile, disreputable businessman Van Alten is after Sally, and tries to pressure her into marrying him by threatening to release letters he says will embarrass her father.
