Choa is a mermaid who’s never fit in because of her unusual problem-she can’t swim! So she abandons the ocean and her tail, for high school and a pair of legs. However, her new life hits a snag when another student discovers her secret. Fortunately, that student happens to be Soo, the star of the high school swim team. Rather than expose Choa, he offers her the chance of a lifetime, free swimming lessons for a mermaid!
