Bill is addicted to cigarettes. When Mr. Hadley has been given a present of a large box of monogrammed cigarettes. Bill helps himself. Later in the day Mr. Hadley leaves his gold watch on his desk and Bill accidentally knocks it off onto the floor. He hastily takes it to the jewelers to be repaired. Mr. Hadley misses the watch and supposes it to have been stolen. He also misses some of the monogrammed cigarettes and inquires of Ethel if she knows anything about it. Bill overhears Ethel being quizzed and slyly slips his remaining cigarettes into Ethel's purse. Later he takes some more for himself and is afraid to tell of the broken watch. The police are notified and told to look for someone smoking or having in his possession the missing monogrammed cigarettes. Bill, smoking in the alley, is relieved of his cigarette by a sneak thief who is promptly arrested when seen smoking it. Ethel meets a young man and in taking out her handkerchief the hidden cigarettes fall to the ground and are appropriated by the young man who is also arrested with Ethel as an accomplice. At the office, Mr. Hadley finds Bill giving a smoker to his boy friends and the mystery of the "stolen" watch is satisfactorily explained.
