Sister Mary Patrick, Sr. Mary Robert and Sr. Mary Lazarus visit Dolores – a Las Vegas singer – during her show, asking her to return to the convent. Delores initially declines, but changes her mind when she hears that Mother Superior is in a desperate situation. Upon their arrival at St. Francis Academy in San Francisco, Mother Superior asks her to teach music to a class of rowdy teenagers. At first, the students play tricks on her, but they eventually grow to like her.

During the course of the school year, Dolores – as Sister Mary Clarence – discovers their musical talent and decides to organize them into a choir.

Sister Mary Clarence obtains use of the school's old music room. As the other sisters help clean it up, they discover old trophies and ribbons the school won from the All-State Music Competition. They find out the competition still takes place in Los Angeles, and convince Sister Mary Clarence and the students to enter, in the hopes they can save St. Francis from closing. As the group heads to the competition, the school board discovers that Dolores is actually a Las Vegas singer and head after them to withdraw the choir from the competition. Father Maurice – the principal – is greeted by the students who think that he came to support them. He decides not to withdraw the choir, despite the wishes of Mr. Crisp, the head of the school board.

The choir sings in the competition and wins, and afterward learns of Sister Mary Clarence's true identity.
