In the past two years, things have changed for the Baker family. Lorraine wishes to live in New York as she studies in college and Nora, their oldest daughter is now married to Bud McNaulty, who wants them to move to Houston after Bud's new job promotion. Feeling the family is starting to break apart, Tom decides to take the whole family on one last vacation to help them bond, but it seems everything during vacation goes wrong. The family soon places the blame on Tom who they say has a very odd parenting style, even spying on his daughter Sarah during a movie date. Tom then decides to bring the family together with one last event, the Family Cup Games.
