Plot
In a dark hospital room, a present is given to Su-hyeon, whose remaining time on earth is finite: a wig her sister Ji-hyeon has bought for her, for she has no hair due to her cancer treatment. Stunned by the glossy wig, Su-hyun slowly puts it on. Immediately, in the mirror she becomes an attractive girl, and a strange atmosphere overwhelms her. From that day on, she regains her vivacious spirit, though this worries Ji-hyeon, since her sister now looks like a stranger to her. When her friend Gyung-joo borrows her wig and is found dead, Ji-hyun notices her beloved sister changing more and more into a different person...
