This movie was made about a little more than five years ago, but I kind of remember what it was about. The only things I remember were the boy was a mermaid, but he didn't know till he got older. He was on his high school swim team and started to notice some changes in his body. At the end he gets released back to where he belongs which is in the Ocean. I remember one part where he was swimming and he had gills on his arms and once he touched this metal part it like shocked him. I can't remember much of it, but I do remember that is was a really good movie.
