Her Wayward Parents (1917)

Synopsis

Father and Mother Lennox are a contented old couple, until daughter Jane comes home from college imbued with a passion for hygiene and an unswerving sense of duty toward them. With a book, "Old People and Their Care" as her guide, she puts them through a course of exercising "sprouts," orders hygienic meals, throws wide the windows to cold winds, and upsets their well-ordered comfort.
