The Singing Tomboy

Anastasia Wright is 17 years old and has a fraternal twin called Lucy. They are basically polar opposites: Lucy loves to wear make up and go to parties and is an average B student, Anastasia on the other hand, loves sports, wears make up only on occasions and is a straight A student. But things change when someone enters Ana's name into a school singing competition that Lucy had already entered, so they have to battle it out with eachother and win the competition. The fact that more than half of the school is taking part in the contest doesn't help.
