Not your all-American girl

Sixth-graders Lauren and Tara have always done everything together so it is only natural that they both try out for their middle school musical play, about an "all-American" girl in 1958; Tara gets the lead role, as usual, because in the teacher's mind Lauren, half-Jewish and half-Chinese, does not fit the image of all-American girl--Lauren is hurt but resolved to support her friend, but her two grandmothers are furious and they intend to do something about it.
