Korean folk horror tale of twin sisters striving to win mother's love.
While running from village kids, Hyo-jin and her sister So-yeon fall into the lake. The twin’s mother tries hard to save them both, but manages only to save So-yeon, who ends up alive in a coma. Ten years later, a man named CHOI is murdered mysteriously as he is heading home from a social gathering. And at the very moment, So-yeon wakes up from a coma without any memory of her childhood and even of her sister Hyo-jin. Not long after So-yeon’s recovery, more people in town get killed and people suspect So-yeon of the murders. Her husband-to-be Hyun-sik, in truth, rather misses the dead sister Hyo-jin. As driven into a corner, So-yeon’s jealousy of her sister deepens again.
