Plot
Two years after Tom Baker resigned from his head coaching position, his family begins to undergo many changes, beginning with his daughter Lorraine's desire to study in New York City after her high school graduation. The family's oldest daughter, Nora, is now married to Bud McNulty and pregnant with their first child; they intend to move to Houston because of Bud's new job.

Feeling the family is breaking apart as the children grow up and move away, Tom persuades them to take one last family vacation all together at Lake Winnetka, a fictional lake in Wisconsin. The family finds that their old cabin is currently owned by a man named Mike Romanow. Tom's old rival, Jimmy Murtaugh, his new wife Sarina, and their large family (with "only" eight kids) are also vacationing at the lake for the summer; Jimmy is also friends and neighbors with Mike Romanow. Jimmy constantly flaunts his wealth and success to Tom, as well as the accomplishments of his children, often suggesting to Tom that his are less successful because of his parenting style. They get into many incidents, several of which are accidental: Mark Baker, along with Kenny Murtaugh, crashes into a tennis court with a golf cart, Sarah Baker is caught shoplifting in a gift shop, and Mark accidentally sets off a backpack of fireworks, causing widespread panic, especially when it is thrown into a boat, igniting its engine and causing it to explode.

Jimmy again brings up the topic that Tom needs to be more strict with his kids. Tom is angered by this, and he and Jimmy decide to settle the matter at the Annual Labor Day Family Cup. Tom trains the kids for days, not realizing they are miserable. Sarah and Elliot Murtaugh watch Ice Age together, but are spied on by their fathers, which ultimately results in them getting into an argument and humiliating their children. Upon returning to the Bakers’ cabin, Sarah is furious and refuses to compete for Tom in the Cup. The children are angry with him, not only for spying on Sarah, but also for ruining the entire trip because of his competitiveness with the Murtaughs, and Tom's wife Kate laments that the two pulling with their parenting has only torn the entire family further apart.

The next morning, Tom goes to the Cup to compete with Nigel and Kyle, the only two still willing to go. However, after discovering an old "Team Baker" flag, Kate and the rest of the kids show up, showing they forgive him and are willing to compete. After the events, however, the Bakers and the Murtaughs are tied for first; a tiebreaking canoe race is announced, in which every family member must compete. During the canoe race, Nora goes into labor; the Murtaughs want to help, but Jimmy, sensing the opportunity to defeat Tom once and for all, refuses to do so. The Murtaugh children jump out of the canoe to help the Bakers. While arguing with Sarina, Jimmy reveals he was jealous of Tom being the popular one when they were younger. Eventually, Sarina convinces him to help and the two families work together to get Nora to the hospital. Bud, Lorraine, and Kate go with Nora in the delivery room, while Tom, Jimmy, Sarina, and the rest of the kids stay in the waiting room. While talking with Jimmy, Tom realizes that he has to let his kids grow, but wherever they go, they will always be with him, and he will always be with them. Nora then gives birth to a baby boy whom she and Bud name Tom in honor of his grandfather, who has shown them that "there is no way to be a perfect parent, but a million ways to be a really good one." Bud announces that he and Nora have bought "The Big House", the vacation home that the Bakers had been renting. Nora, Bud, and baby Tom leave for Houston a few days later.
