A teenaged lad tries to come to terms with the fact that he is "Selkie" -- a seal-human hybrid -- in this Australian family movie. Jamie Duncan (Shimon Moore) moves with his marine-scientist mother Iona (Celine O'Leary) to Jackson Island. Iona heads up a research center on the island, and Jamie soon encounters her dour assistant (Edmund Pegge) and an evil tuna fisherman (Michael Habib). En route to the research center, Jamie hits it off with Samantha (Chelsea Bruland). Their budding puppy love is thrown for a loop when Jamie jumps into the ocean to save Samantha -- and turns into a seal. After his grandfather explains his unusual lineage, Jamie resolves to find the secret potion that will make him all human.
