Bitna, 7 years old little girl, visits her Grandpa the fish’s house and finds a big dog called Chin-chin. Bitna and Chin-chin set out on a trip to the sea together.

Upon visiting her grandfather’s house, Bitna finds a dog named Cheuncheun. She frees the dog that has been kept in a room and determines to travel the sea with him. The extraordinary adventure of the little girl and the big dog seems to come to a halt due to the villagers’ interference, but their trip continues and creates a magical moment. Even though it's not a fresh setting, the images of them roaming around move our hearts. [LEE Hookyeong]
