"Old Man" Davis, a rheumatic grouch, tells Herbert, his daughter's fiancé, that he will have none of him, and to leave his premises. Herbert, however, through a doctor friend, secures a patent medicine that guarantees the cure of rheumatism. Herbert informs Mr. Davis of his remarkable discovery, and is promised the hand of Gertrude, providing he can cure the old gentleman. Over-enthusiastic, "Old Man" Davis takes more of the medicine than the law allowed.
