Having lost her voice in an accident, Ji-hyun devotedly nurses her younger
sister, Su-hyun, whose remaining time on earth is finite. Then one day, the
lives of these two loving sisters change dramatically. As a present to fill the
emptiness left behind by chemotherapy, Ji-hyun buys Su-hyun a wig. From
that day on, Su-hyun gradually regains her vivacious spirit. However, it is no
ordinary wig: the traces of a tragic death and the deceased one's memories
remain with this wig. It starts to change Su-hyun into an entirely different
person and Ji-hyun watches over her with worry.
