Director John Sayles adapted Rosalie Fry's book "Secret of the Ron Mor Skerry" for this film about a young girl who is sent to live with her grandparents on the Irish coast across from Roan Inish, the island where her ancestors once lived. She soon discovers the myth of the selkies, seals with the ability to turn into humans, and her investigations of the myth lead to more discoveries about her family's history.  (IRE133, $24.95)
