A girl who used to love playing on the beach on Jeju Island is now an old woman who cannot leave the sea. She has lived as a ‘haenyeo’(woman diver) all her life and diving is still her favorite pastime and a grateful job. Grandma Ocean is an animation of the stor y of Gang Du- gyo, an actual haenyeo, told by Gang Du- gyo herself. She says that ‘taewak ’, which is the case for storing seafood’ is actually their spirit box and that going diving means going to the other world to make money, and a ritual to dif fuse fear are some of the things she deals with. There is no ethnographic exploration into the lives of haenyeo but the film conveys lighthear tedly the sentimentalit y of haenyeo who interact with the world under the sea all their lives and can never give up diving and the hear t of a haenyeo who still gets excited like a lit tle girl.
