It's 1956 Brooklyn, where Jules and Sophie Berger live in the same apartment as their daughter, son-in-law, and two grandchildren, who experience meaningful events in this opener: his budding social life separates 14 year-old Alan from his less mature friends, while 9 year-old Nathaniel meets Dodger great Gil Hodges.

For Sophie, the funeral of her Uncle Ira (whom no one really liked) requires total family attendance—on the Sunday of Alan's Dodger game date with Katie Monahan.

Alan is asked to be on a television show that showcases young baseball players in a competition at Ebbets Field, winning him the chance to meet several Brooklyn Dodgers players. Depressed after not winning the competition, he goes to visit his father at work while the family worries about his whereabouts.

During the family gathering for Succoth, a Jewish thanksgiving ceremony, free-spirited Aunt Sylvia, who follows the ""beat"" movement, announces that she is getting a divorce from her husband. Sophie is horrified when Sylvia says she is stifling in the marriage and desperately tries to talk her out of her decision.

Katie is so upset that her school science project didn't work out properly that Alan ""fixes"" the results for her, which only serves to make her more upset; meanwhile, George and Grandpa annoy the women in their lives when they resort to doing a favor for Sid's cousin Morty (the loan shark) to get tickets for a Harry Belafonte concert.

Neither Katie's parents nor Alan's grandparents think they should be dating out of their faith, so the desperate kids arrange a meeting between the two families. Things go from bad to worse during the uncomfortable dinner when obnoxious Uncle Willy and his wife Miriam turn up at the same Chinese restaurant the families have chosen as neutral ground.

While their elders are away at a wedding in Boston for the weekend, Alan and Nathaniel are trusted to stay on their own. Then Warren, inspired by an article in Life, comes up with an idea for a ""dinner party"" with Katie and her friends ""the Marys,"" and Nathaniel is excluded. But the tables are turned on the boys when Nathaniel gets sick and the girls pay more attention to him than to them.

Nathaniel is upset when Jules and Sophie's cousin Myron, once partners in the hatmaking business, have a falling out at the weekly Friday night poker game and stop speaking to each other. In the meantime, Uncle Joel is helping George and Phyllis get through an income tax audit.

On a ""once in a blue moon"" Saturday, George is off work, so Alan and Nathaniel look forward to having some fun with their dad--but the adults decide ""Family Chore Day"" comes first. Well...that is until Grandpa, George, and the boys end up test driving a beautiful red Buick to Coney Island and Phyllis and Grandma play hookey at the new Danny Kaye movie with a stop for ice cream at Sid's afterward.

Sid wants to branch out into catering and hires Alan, Warren and Benny to be waiters at his first wedding, but when Benny makes himself sick sampling the food and the three boys begin participating in the entertainment, Sid finally gets fed up. When Alan's dad and grandfather rush to help out, Alan--and finally Warren and Benny--learn a lesson about responsibility.

The weekly ""Cousins Club"" meeting may survive the devastating news that Jackie Robinson has been traded to the arch-rival New York Giants (from the Brooklyn Dodgers)until Aunt Miriam chooses that time to reveal that Uncle Willy has cheated on her with a model named Cookie LaBarbera.

After his beloved fourth-grade teacher Miss McCullough announces at ""Open School"" that she is getting married and leaving for Japan with her serviceman husband, Nathaniel is not only devastated, but he refuses to adjust to his new teacher--to the point where he is sent to the principal's office.

Meanwhile, Benny's conscience bothers him after he forges a note from his mother.

Benny tells Alan that Katie is now his girlfriend and they can't be friends any longer; meanwhile, Karen Frankel further misunderstands her relationship with Alan, and, during preparations for the rummage sale, Aunt Sylvia and Sid seem to be hitting it off.

Katie finally explains her feelings to Benny and eventually he and Alan resolve their differences--after he makes peace with Karen and Benny has a heart-to-heart with Grandma. Meanwhile, the rummage sale wildly achieves its goal, and Sid invites Aunt Sylvia back to the store for champagne.

Phyllis and George allow Aunt Sylvia to take Alan into Manhattan to Nero's Coffeehouse to hear Jack Kerouac recite poetry, but when they are late coming home, Grandma and Grandpa follow them, whereupon Sylvia and her beat friends and the older folks discover they aren't so different after all.

The results of the NY Standardized Aptitude Test rattle the boys, especially Benny, whose career profile turns out to be ""forest ranger,"" but Alan is even more shocked when he's accepted at the Bronx High School of Science. Feelings are mixed from other quarters although the plethora of relatives Phyllis phones are delighted--but the most reluctant of all may be Alan. Meanwhile, the Cousins Club has agreed to finance Sylvia's new poetry magazine, ""Sludge""--if Sophie doesn't explode at what looks like Sylvia's growing romance with Sid.

Alan's reluctance to go to the Bronx High School of Science worries George enough that he has a talk with Mr. Greer about the pros and cons of Alan's attending, but when Alan finally gathers his courage and tells his mother he doesn't want to go, the confrontation hurts both of them--putting George in the middle. In the meantime, Benny seems to be reconciled to being a forest ranger, in a big way.

On the Sunday they were planning to go to the Statue of Liberty--Nathaniel has been studying it in school--it pours, so George proposes that they hold ""Rainy Day Indoor Olympics"" in the hall, but Ring-a-Lievio, hallway hockey, and Johnny-On-the-Pony seem tougher on George than they are on the boys; meanwhile, a hurt cousin Bernard awaits news of his fiancee, who was supposed to meet him on the Number 63 bus and never showed up and Phyllis and Jules try to assemble a jigsaw puzzle of the Statue of Liberty.

During a crucial basketball game between Rigo Park and the Jewish Community House junior league, Alan wins two free throws after one of the opposing players makes a foul. One successful basket will tie the hotly contested game, two will win. But as Alan psyches himself up for the task, his imagination runs wild, first in thoughts of what events led up to the game, then in a series of wild flash fantasies in which he fears that if he blows the shot, he will ruin his whole life.
