The Secret of Roan Inish

This is a safe, quiet movie the entire family can enjoy. It was made in Ireland, and as such is slower and quieter than most American movies.
It is about a little Irish girl who moves to live with her grandparents. While there she unwittingly stumbles upon the mystery surrounding the island the family used to live on, called "Roan Inish" (Island of the Seals). As she slowly solves the mystery, she brings healing and unity back to the family. In this movie the mythical creature is a selkie, not a mermaid. The selkie lives in the form of a seal. On occasion she climbs up on a rock and removes her seal skin, revealing a beautiful woman. So this movie is a little bit different, and you will never look at a seal the same way again.
