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.

Kevin's first day of high school is not all it's cracked up to be. He tries to set himself up as the class clown, but it backfires. He is hassled by a nerd and his new teacher, Mr. Botner. Even Winnie can't make him feel better.

While Kevin is asked to consider his future, Wayne makes a decision to leave school and join the army. Jack and Norma try to talk Wayne out of it, but he won't listen. Wayne and his friend Wart go together to the army testing station. Jack follows and apologises to Wayne for not being a better father to him.

While Kevin tries to take his relationship with Winnie another step, Wayne's friend Wart returns from Vietnam a changed man. Kevin decides to steal the opposing team's mascot at the homecoming football game, but the childish prank is overshadowed by a realization of how Wart has been affected by the war.
