IT'S BAD, IT'S SAD, AND NOW EVERYONE'S MAD!
Nancy and her friends are practicing for the big ballet recital. They're so excited -- and nervous, too. Especially Bess. She loves her beautiful mermaid costume, but she can't seem to learn the steps. And now the girls may not get to perform at all!
The tape with the special music is missing, and almost everyone blames Bess. Nancy has just two days to find the tape, help her friend, and save the ballet!
