Doctor Jackson, "Dr. Jack" for short, is a poor country doctor from Magnolia Meadows who believes that most illness is psychosomatic, and that anyone can be cured if one's mind is put to it.  A number of patients in the town receive pick-me-ups from Dr. Jack, and their smiles are is payment.

Meanwhile, the Sick-Little-Well-Girl has been sheltered from light and excitement for years, under the "time and skill-mostly time" of Dr. Ludwig von Saulsbourg.  Dr. Jack first encounters Miss Haskell, her father and her doctor, at an eatery, and it is love at first sight.

A lawyer, Jamison, is impressed by the young physician; his mother was one of Dr. Jack's patients, and the lawyer just happens to be friends with Mr. Haskell.

Jamison suggests a consultation to Haskell, later warning Dr. Jack, "The doctor she has now is an old fogy-a four-flusher!  Use your own methods.  Pay no attention to vonSaulsbourg's ideas."

When Dr. Jack arrives at the Haskell home, the infatuation grows between him and the girl, but her doctor convinces Mr. Haskell that he is the better of the two physicians.  Dr. Jack is shunned from the home, after "accidentally" kissing Miss Haskell while examining her eyes too closely.  He feels, though, that with a little excitement in the house, the Sick-Little-Well-Girl will be as good as new, so he devises a plot, surrounded by a police search for an escaped lunatic, Lumpy Logan.
