Doctor Jack Jackson is a nice young country doctor who prefers to use common sense and his sunny personality to cure his patients, rather than pills and potions. Then, a rich father asks Dr. Jack to look after his daughter.
Dr. Ludwig von Saulsburg, an eminent specialist, has been caring for the girl by keeping her in a darkened room and prescribing various medications. Dr. Jack soon realizes that there is nothing wrong with the girl that a little sunshine and excitement won't cure.
And, Dr. Von Saulsburg, who has been making a comfortable living off of the girl's family, is exposed for the fraud that he is.
