Mary gets an engagement ring and a phone call from Matt, a freshman at UCLA, but doesn't tell anyone in the family about the ring or why Matt is calling. So what's going on? As Donna says, "Alex, our daughter has a secret."

Alex lays down the law when Jeff and Mary slack off on their responsibilities at home and their schoolwork. Now Alex is furious when it appears that Mary didn't come home from a bowling date with Roger on time.

Jeff finds out the reason why he wasn't made a member of a club: He is friends with a boy no one else likes.

Donna is too excited to sleep because Alex is giving a speech at a convention. While trying to sleep on the plane, Alex gives Donna a tranquilizer to help her sleep, which leads to an embarrassing chain of events.

Alex is hurt that Jeff likes the new neighbor.

Donna makes Jeff take trumpet lessons when she discovers he has perfect pitch. Jeff would rather be on the track team.

While Alex was the ""belle of the ball"" with his fantastic dancing at the Woman's Medical Auxiliary Dance, the dance cost more to produce than the income from ticket sales provided. Each member agrees to contribute $27 using her skills in moneymaking to make up the budget shortfall. Donna will sell 54 jars of her famous pickle recipe at fifty cents per jar and donate the money to the Auxiliary. Will Donna's plan work?

Donna is away and Alex has to manage the house and children.

Donna's old school mate, who has been a single career woman all these years, is now engaged to a doctor. She visits Donna to see what life is really like for a doctor's wife.

Jeff wants to keep a cat that followed him home, so can Harry the Cat stay? The Stone family will decide by using the democratic process.

Donna mistakenly accepts an invitation to 'culture vulture' Lydia Langley's cocktail party, at which Lydia mentions that she also conducts a book discussion group. She goads Donna into joining it and then reporting on Tolstoy's "War and Peace" at her first meeting. Donna then attempts to immerse the whole family in culture.

Dilemma in the Stone household: How to discipline the children without having Donna look like a villian by meting out the punishments, or having Donna look like a squealer when Alex does .

Donna gets cornered into accepting an invitation from a couple that neither she nor Alex really care for. Alex refuses to go, sparking an argument that they try to keep quiet from the children.

Alex and Donna chaperone Mary's date with a college man.

Lately, all Donna has been hearing is how wonderful Alex is, and how lucky she is to be his wife. After a while, this gets Donna wondering if what people really mean is that Alex got the short end of the stick by marrying her.

Jeff's class has a new teacher, Miss McGuinness. The boys in particular complain that she is too strict, so Donna meets with the new teacher to get matters settled.

Jeff causes problems for everyone else in the house due to his selfishness and inconsideration for others. Because of this he gets a lecture, which he blows off. But then these same issues end up making him go overboard on being a model son when he fears the repercussions of hurting someone.

Mary vows not to go to the school dance unless Ellen has a date for the dance. Ellen is rather plain so Mary goes to work to transform Ellen into a glamorous young lady.

Donna becomes offended by the way people seem to use the word ‘housewife’ condescendingly.

Alex's Uncle Dan takes a break from traveling all over the world. Jeff likes the idea of going to Alaska, Saudi Arabia, Malaya, Australia, and doing whatever he wants, just like Uncle Dan. Jeff decides to join him. Will Donna and Alex allow him to go? Would you believe, yes?

Donna tells Emily, the town gossip, that Kay Watson is having a baby. Then Donna learns from Alex that Kay is keeping it a secret so that she can stay working longer. Donna is crushed, knowing that she may have let Kay's secret out.

Mary does a kind deed by encouraging a shy, insecure fellow student, Kenny, to appear in the school play. When she does, he ends up being paired with her in a dance number. But she regrets her good deed because she’s worried about how they’ll appear next to each other, as he’s shorter than her.

Donna has trouble deciding whether or not buy a new dress.
