Mother Simplicia (Rosalind Russell) is the head nun at an all-girl school. Aided by the young Sister George (Stella Stevens), the two try to convert the wayward girls to prim and proper ladies with a solid religious foundation. Rosabelle (Susan St. James) and Marvel Ann (Barbara Hunter), are the leaders of the teenage girls who often rebel against authority.Arthur Godfrey plays the Bishop, and Milton Berle provides a hilarious cameo as a film director whose big cowboy chase scene is ruined by the arrival of the girl's school bus. Farriday (Robert Taylor) is the helpful neighbor, and Van Johnson is the priest who heads the school for boys in this mildly amusing comedy. Tommy Boyce and Bobby Hart sing their self-penned title track.
