Sci Fi is probably the genre least visited in Korean cinema. Eom Tae-hwa, however, decided to tackle the category, and by using a rather unique perspective, manages to transcend its borders and present a great film.
Thirteen-year-old Soo-rin has moved to a remote island with her stepfather, who is overseeing a large construction there. She befriends Seong-min, a local orphan day, and as the two of them start sharing their dreams, fantasies and a common interest for the occult, their relationship becomes something more than friendship. One day, Soo-rin follows Seong-min and his three friends into a visit towards the construction site, deep in the mountains, in order to witness a big explosion that is about to take place. During their trip, they stumble upon a cave and decide to explore it. In a lake inside the cave, they find an egg, which, according to a local folktale, contains a time-eating goblin. Eventually, an accident occurs, the egg breaks, and the three boys end up in a continuum where time seems to have stopped. In the beginning, they have fun doing whatever they like, but as they realize they cannot escape and the years pass, they start worrying, and sickness and depression takes over. After a number of years, Seong-min manages to return, but he is now a full- fledged young man, while everyone else is of the same age, since just a few days have passed in the real world. As he revisits Soo-rin, he has to face society, her father, and the police, all of which consider him a dangerous pedophile.
