 Coach Graham Lubbock, introduced on "Growing Pains," decides to move his large family out to California when his wife becomes pregnant with their eighth child. The Coach takes a job at the Catholic school where his five daughters and one son are enrolled. The oldest daughter, Marie, wants to become a nun; Wendy and Cindy are the exact opposite, and enjoy much attention from the boys at school; Connie is an intellectual idealist; J.R. is the lone boy (aside from one of the babies) in the group of girls; he and Sherry are the most mischievous of the group. Eventually, the four oldest girls form a singing group, with Wendy and Cindy s personalities often showing in their performances, even through Connie and Marie.
