章武Yi-jung is in her late twenties and still lives with her mother. Having raised her daughter alone, Su-kyung is now ready to start a new life with her fiancé and leave the past behind. Not so Yi-jung, who from an early age has all too often had to serve as an outlet for her irascible mother’s frustrations. The many years of disregard have left her with a crippling mixture of suppressed feelings towards her mother from whom she simply cannot break free. When an argument between the two escalates in a supermarket car park, Su-kyung hits her daughter with her car. Just an accident, the mother claims. Malicious intent, Yi-jung retorts. This rebellion marks the beginning of an arduous process for both women to cut the cord.
