Molly wakes one morning to find her house empty. Her father has been out fishing in stormy seas and hasn't returned from his trip. She takes her most precious possessions down to the harbour; a brass locket containing twenty little cowrie shells, a photograph of her father and her beloved doll Isla to offer the sea in return for her father's safety. A tale of love, sacrifice and hope. -- Cyngor Llyfrau Cymru
