All I remember was that it was filmed in part of Marysville CA and it was about two girls (about 8 or 9) meet at a camp and become friends then one night they decide to go swimming and one of the girls (Amelia) says she can't swim but the other says come on you can do it! So Amelia goes in and ends up drowning & dies. Later on the mother of Amelia thinks that Amelia's friend is Amelia and takes her home I believe. And then starts calling her Amelia and the girl yells "Im not Amelia!" it's a good movie I just can't remember what it was called any help?
