Follows the legend of the three daughters. One night, a crazy mother kills her three little girls. Some years later in a mental hospital, she is murdered with three types of cold steel arms. Witnesses say that it's done by three teenage girls. The ghosts of the dead daughters take revenge on their mother, but their thirst of revenge isn't quenched and their hatred does not dispel. A deadly chain reaction is put into action: those who saw the daughters' victim last become the object of their close attention for three days. As soon as the person does anything wrong or unfair, the ghosts hold their merciless trial.
