Korean supernatural horror from directorial debutant Won Sin Yeon. The film tells the gruesome tale centering on two sisters and the demonic wig that comes between them. Each sister, it seems, has suffered a terrible trauma: Chi Hyon (Seon Yu) can no longer speak due to a terrible car accident that damaged her vocal chords, while her younger sibling Su Hyon (Min-seo Chae) has been diagnosed with cancer with little chance of recovery. When Su Hyon loses her hair due to chemotherapy treatment, Chi Hyon decides to give her younger sister a beautiful wig to help her regain her confidence. Immediately, Su Hyon begins to change in ways her elder sister never expected.
