Mad is excused from school by Harriet, who forges an excuse note to bring Mad to a TV studio.
Harriet and Mad plan to avoid Mad's mother at the studio by sitting at the back next to the emergency exit.
At the studio parking lot, they are informed by an attendant, Seymour Browne, that they likely won't be able to get in due to the large crowd.
Despite the potential unavailability, they are ushered inside by Walter Pine's secretary and are seated in the front row.
Mad witnesses her mother, Elizabeth Zott, host her cooking show, "Supper at Six," with great presence and authority.
Elizabeth educates her audience on the chemical composition of meat while Mad experiences pride and a tinge of jealousy.
Elizabeth addresses a viewer's letter about vegetarianism and the ethical implications of eating meat, before returning to the topic of meat preparation.
The secretary takes Harriet and Mad to meet Walter Pine. Pine questions why they are at the studio instead of school.
Pine discusses the consequences of fame and how Elizabeth wants to protect Mad from negative aspects of celebrity life.
Mad asks why her mother is so popular, and Pine attributes it to Elizabeth's frankness and everyone's unexpected interest in chemistry.
In a live Q&A, Elizabeth, asked about her favorite grace, openly admits to being an atheist and expresses gratitude to those who make meals possible.
Mad's mother ends the show with strong advice, and Walter's phone starts ringing incessantly, indicating potential fallout from Elizabeth's statement.
