Office drone Frank Daniels takes a spill off the trolley. Only a blood transfusion from a vigorous man can save him, so Irish neighbor L. Parkes, who knocks his wife down the stairs and gives a flagging workman enough money to buy some stew and get his strength up, is volunteered. Whereupon Franks starts acting like Casey, and vice versa.
The IMDb credits the direction of this movie to Larry Semon. Contemporary sources say that Van Dyke Brooke directed. The on-screen credit is Arthur Ellery, who was an actor and director for Thanhouser. The story likewise shows an utter confusion about eugenics, the pop culture idea that you can breed people like Gregor Mendel bred peas, and the belief that someone else's blood can affect your temperament. That is the humor in it.
