When Kevin's birthday party is scheduled for the same day as Paul's Bar Mitzvah, Kevin feels put out, but also becomes interested in family traditions.

Paul's sister Debbie needs someone to take her to a cotillion and Kevin is guilted into the task. Meanwhile, Paul, Doug and Randy go to the football game to watch cheerleader Donna Delgado.

As Kevin graduates from Junior High, he wants to believe nothing will change, but he learns that things can and do change when he discovers Paul is going to a private school in the coming year. Winnie is also anxious about the future. And Kevin has to drive Mrs. Heimer to the hospital when she goes into labor.

A clip show of highlights from Kevin's years in Junior High. Including clips from "Don't You Know Anything About Women," "The Glee Club," "Just Between You and Me... and Kirk and Paul and Carla and Becky," "Summer Song" among others.

The Arnold and Pfeiffer family go on a joint family trip. Kevin meets a wild young girl who smokes! Kevin and Cara have a good time together, so much so that he ditches dinner with his family to see her one last time - expecting to never see her again.

The Pfeiffer and Arnold families have always been friends, but that friendship is threatened when the Pfeiffers come into a lot of money due to a real estate investment that Jack Arnold passed on. When the Arnolds are invited to the Pfeiffers' country club, Jack cannot handle it. Norma saves the day with a toast to the families' continuing friendship
