Salajin sigan

In a country village, Soo-hyuk, a primary-school teacher adored by his pupils, and his wife, the sweet and shy Yi-young, seem to be the ideal couple. However, the latter is afflicted with a strange evil. At nightfall, her personality changes dramatically, as if she were possessed, and in the morning she becomes the young woman everyone loves again. When one of the curious villagers comes across a Yi-young in judoka mode, the community, frightened by her unpredictability, decides to build a cage for her in the attic of her house. Unfortunately, this idea quickly turns to tragedy. Detective Hyung-gu arrives in the village to investigate the fire that claimed the couple’s life. Although the case seems complex, the policeman can't anticipate what awaits him there. He might even come to wonder if he’s really himself... (Fantasia International Film Festival)
