While Flora Winslow, a widow is engaged to Bunny, she attends a lecture on eugenics and decides that her intended husband is too fat. She tells him he must reduce, and as she wishes to become stouter, they agree to attend Dr. Sweatem's Sanitarium. In the gymnasium they are introduced to Violet Small, a stout young lady, who starts a flirtation with Bunny. The widow and he are then given some very strenuous exercise, with the various apparatus, cross-country runs, etc. Flora becomes Jealous of Bunny's attentions to Violet and quietly suggests an idea to the doctor, who agrees with her. Bunny is invited by the doctor to take a ride in his automobile. Violet also asks to go and the doctor consents. They whiz over the roads until opposite a sign post reading, "10 miles to Dr. Sweatem's Sanitarium." There the doctor asks the pair to alight, throws in the clutch and is off for home, shouting back the gladsome announcement, "You can both have a nice walk home.'' The two wearily trudge back the way they came. After being chased by a wild bull, tearing their clothes, on barbed wire and falling into a stream, the two sit down to rest. Bunny's beating heart refuses to be still until he has declared his love for the fair Violet. She consents to become his wife and on reaching the Sanitarium, they decide to elope. He forces a chauffeur to drive them in his machine to the nearest minister, where Bunny and Violet are soon united in the bonds of wedlock, each content with the other.
