Accidentally tearing up an important letter, Lucy (Lucille Ball) wonders exactly who is planning to pay her a visit. Much to her chagrin, the "mystery guest" turns out to be her zany Aunt Agatha (Mary Wickes), an overbearing physical-fitness freak. Driven to the brink of madness by Aunt Agatha's strict exercise regimen and horrible health food, Lucy must cook up a scheme to rid herself of her martinet relative.
