Richard Marston, stockbroker, is one morning attacked with a fit of nervous breakdown. He sends for the doctor, who gives temporary aid, but tells him to immediately go south and rest up or the consequence will be serious. Marston, his wife, and Roy, his son, pack up and hasten to a bungalow at Snake River, Florida. A few days pass and Roy encounters Dolores, a girl who runs a motorboat for hire. She lives with her father and mother and little sister, Rosita, in a shack near the shore. The baby girl visits the Marstons and is petted and treated kindly by them. Marston discovers Roy's attachment for the boat girl and is annoyed. The little girl falls sick and Marston visits the shack and gives the mother money. The doctor is called and advises that if the child gets worse that he be sent for quickly. Marston receives a message that his stocks are being raided and he must catch the next train for New York. He hastens to the boathouse to get Dolores to take him to the nearest station, which is 30 miles up the river. Just at that time Rosita gets worse and Dolores must go in haste for the doctor. Marston storms and demands that he shall be taken to the railway. He has a million at stake, he offers $10,000 for the service of the boat. Dolores refuses the offer and turns her boat down the river for the doctor. The child's life is saved and Marston's millions also. He then resolves that Dolores is the right sort of a girl to be his daughter-in-law.
