Two twins are in a ballet class. One feels that the teacher never notices her, even though she is a good dancer. The other twin ends up getting the lead role in the performance of a play. The first twin gets jealous. She also skips out on things like helping out another girl. They go through many twin fights and eventually come to some sort of truce. At the day of the performance, the girl in the lead fakes a sprained ankle to let her sister take the lead. Then she is "miraculously healed" and can act in the minor role. They all end up happy together. There is some relatavle experiences with sibling jealousy, even if the final resolution is a little bit far fetched.
