Jack Watson, a wealthy young clubman, has the reputation among his friends of being indolent and indifferent. One night he refuses an invitation to the theater and supper afterwards, and taking a taxi, drives into the country. An accident to the machine causes a delay, and Watson is attracted by a fine house nearby. He strolls near, and is looking up at the lighted windows when he sees the face of a beautiful young girl appear for a moment and then withdraw suddenly, as though its owner were dragged back by unseen hands. Watson investigates and finds that the girl is a prisoner, surrounded by the house servants who have bound in the same room, a well-dressed old man, evidently her father, and are threatening to kill the girl if he will not reveal to them where he hides his valuables. One of the men comes out to the garage to enlist the help of the chauffeur. As soon as he is gone, Watson overpowers the chauffeur, and disguising himself in his livery and goggles, goes to the house. The girl and the valuables are entrusted to him. But just as he is on the point of leaving, the chauffeur, who has recovered, phones from the garage, disclosing the deception. A fight ensues. The taxi driver, however, comes to Watson’s assistance. They overpower the servants, and Watson wins the friendship of the girl and her father.
