Kevin seeks a rite of passage as his birthday approaches, entering the big teen years.
After Mary leaves an embarrassing phone message on the answering machine of Lester's would-be client, she enlists the help of Rose, Dylan and Travis to erase the tape.
With great reluctance, Kevin agrees to escort Paul’s little sister, Debbie (Kevin’s number one fan) to a cotillion dance.
While the Arnolds and Paul’s family have fun together at a lakeside summer outing, Kevin withdraws from family activities and becomes involved in an adolescent relationship with a local girl.
Change gets the best of Kevin.
