After the disappearance of her mother when she was a baby, 4-year-old Saoirse, who lives on a small island with her father and older brother Ben, discovers a magical coat that turns her into a seal-like creature called a selkie. Having spent the night swimming with the seals, Saoirse is found washed up on the shore by her Granny who decides she and Ben would be safer living in the city. One Halloween night, longing to return home, Saoirse awakens some faerie creatures, leading the two children on a weird and wonderful journey. Beautifully drawn with a bewitching soundtrack, this is an enchanting feast for the eyes and a heart-felt celebration of traditional Gaelic storytelling and folktales.
